recomandare motherboard pt Intel I7 4790K

Da, ai dreptate.
Oricum, prea mult nu cred ca se va simti in jocuri, cu upgrade cpu + motherboard

upgrade-ul de cpu+mobo nu prea in jocuri. dar se va simti per total in utilizare. cred ca mai faci si altceva decat jocuri

o sa vezi tu

Inca o intrebare : actuala placa de sunet - e pe PCI - se va potrivi intr-unul din sloturile urmatoare ?
4x PCIe 3.0 x16 (2x x16, 2x x8), 3x PCIe 2.0 x1

ce placa de baza? ce placa de sunet?

O placa de sunet cu interfata PCI.
Pe o placa de baza cu urmatoarele sloturi : 4x PCIe 3.0 x16 (2x x16, 2x x8), 3x PCIe 2.0 x1

Din pacate se pare ca Skylake nu va benefecia de grafica implementata pe procesoarele din seria Broadwell.



Skylake's iGPU: Intel Gen9

Both the Skylake processors here use Intel’s HD 530 graphics solution. When I first heard the name, alarm bells went off in my head with questions: why is the name different, has the architecture changed, and what does this mean fundamentally?
Not coming up with many details, we did the obvious thing – check what information comes directly out of the processor. Querying HD 530 via Intel's OpenCL driver reports a 24 EU design running at 1150 MHz. This is different than what GPU-Z indicates, which points to a 48 EU design instead, although GPU-Z is not often correct on newer graphics modules before launch day. We can confirm that this is a 24 EU design, and this most likely follows on from Intel’s 8^th Generation graphics in the sense that we have a base GT2 design featuring three sub-slices of 8 EUs each.


Generational Tests: Gaming Benchmarks on Low End

Alien: Isolation
If first person survival mixed with horror is your sort of thing, then Alien: Isolation, based off of the Alien franchise, should be an interesting title. Developed by The Creative Assembly and released in October 2014, Alien: Isolation has won numerous awards from Game Of The Year to several top 10s/25s and Best Horror titles, ratcheting up over a million sales by February 2015. Alien: Isolation uses a custom built engine which includes dynamic sound effects and should be fully multi-core enabled.
For low end graphics, we test at 720p with Ultra settings, whereas for mid and high range graphics we bump this up to 1080p, taking the average frame rate as our marker with a scripted version of the built-in benchmark.

Total War: Attila
The Total War franchise moves on to Attila, another The Creative Assembly development, and is a stand-alone strategy title set in 395AD where the main story line lets the gamer take control of the leader of the Huns in order to conquer parts of the world. Graphically the game can render hundreds/thousands of units on screen at once, all with their individual actions and can put some of the big cards to task.
For low end graphics, we test at 720p with performance settings, recording the average frame rate. With mid and high range graphics, we test at 1080p with the quality setting. In both circumstances, unlimited video memory is enabled and the in-game scripted benchmark is used.

Grand Theft Auto V
The highly anticipated iteration of the Grand Theft Auto franchise finally hit the shelves on April 14^th 2015, with both AMD and NVIDIA in tow to help optimize the title. GTA doesn’t provide graphical presets, but opens up the options to users and extends the boundaries by pushing even the hardest systems to the limit using Rockstar’s Advanced Game Engine. Whether the user is flying high in the mountains with long draw distances or dealing with assorted trash in the city, when cranked up to maximum it creates stunning visuals but hard work for both the CPU and the GPU.
For our test we have scripted a version of the in-game benchmark, relying only on the final part which combines a flight scene along with an in-city drive-by followed by a tanker explosion. For low end systems we test at 720p on the lowest settings, whereas mid and high end graphics play at 1080p with very high settings across the board. We record both the average frame rate and the percentage of frames under 60 FPS (16.6ms).

GRID: Autosport
No graphics tests are complete without some input from Codemasters and the EGO engine, which means for this round of testing we point towards GRID: Autosport, the next iteration in the GRID and racing genre. As with our previous racing testing, each update to the engine aims to add in effects, reflections, detail and realism, with Codemasters making ‘authenticity’ a main focal point for this version.
GRID’s benchmark mode is very flexible, and as a result we created a test race using a shortened version of the Red Bull Ring with twelve cars doing two laps. The car is focus starts last and is quite fast, but usually finishes second or third. For low end graphics we test at 1080p medium settings, whereas mid and high end graphics get the full 1080p maximum. Both the average and minimum frame rates are recorded.

Middle-Earth: Shadow of Mordor
The final title in our testing is another battle of system performance with the open world action-adventure title, Shadow of Mordor. Produced by Monolith using the LithTech Jupiter EX engine and numerous detail add-ons, SoM goes for detail and complexity to a large extent, despite having to be cut down from the original plans. The main story itself was written by the same writer as Red Dead Redemption, and it received Zero Punctuation’s Game of The Year in 2014.
For testing purposes, SoM gives a dynamic screen resolution setting, allowing us to render at high resolutions that are then scaled down to the monitor. As a result, we get several tests using the in-game benchmark. For low end graphics we examine at 720p with low settings, whereas mid and high end graphics get 1080p Ultra. The top graphics test is also redone at 3840x2160, also with Ultra settings, and we also test two cards at 4K where possible.

Intel’s 6^th Gen Skylake Conclusions

The new 6^th Generation Skylake platform from Intel has launched today, and as part of the package there are two new processors, the Core i7-6700K and the Core i5-6600K, a new Z170 motherboard chipset with corresponding motherboards, and also a new market for DDR4 DRAM. The purpose of the Skylake platform launch is to update the mainstream PC market segment for the purposes of better performance and enhanced connectivity.
What is Skylake?

[ http://images.anandtech.com/doci/9483/Intel%20Core%20i7-6700K_575px.png - Pentru incarcare in pagina (embed) Click aici ][ http://images.anandtech.com/doci/9483/Intel%20Core%20i5-6600K_575px.png - Pentru incarcare in pagina (embed) Click aici ]

Skylake is a new processor architecture based on Intel’s 14nm process using the newest generation of their FinFET lithographic technology, and the two overclockable K series CPUs are the first processors to be released into the wild. For some this is mildly confusing, given that Intel launched Broadwell for desktop (a die shrink "tick" from 22nm to 14nm) only a couple of months ago. Broadwell has only acted as a minor stopgap measure, fulfilling the requirements of an upgradable platform and taking the crown of the best integrated graphics processor for a socket. As a result of that minor role, a number of users will see Skylake more as an upgrade from Haswell, the last mainstream processor family that had a long market shelf life.
For this launch and review, details about Skylake have been relatively rare to come by even in Intel’s own press documents, and we are set to hear more details at Intel’s Developer Forum in mid-August. Nonetheless, we have been able to determine that Skylake has a raft of updates, focusing on fixed function hardware to accelerate certain workloads as well as decoupling the CPU and PCIe frequency domains on the silicon to allow for more precise overclocking.

[ http://images.anandtech.com/doci/9483/Combo%20Box_575px.png - Pentru incarcare in pagina (embed) Click aici ]

The platform changes as well. The voltage regulators inside Haswell CPUs move back out on to the motherboard as they generated too much heat inside the CPU. This is good for overclockers, but means the required components on Z170 motherboards, and price, has the potential to go up. The Z170 chipset is the sole chipset being released today, with others coming later in the year. Z170 features an upgrade to DMI 3.0, giving faster CPU-to-chipset bandwidth and enabling a 26-lane high speed IO hub. Of these lanes, 20 can be configured for PCIe lanes under a strict set of rules, giving access to the potential for more functionality on board. Most motherboards being launched today will use these lanes to provide M.2 slots, USB 3.1 Gen 2 ports via controllers, extra networking, extra PCIe slots and SATA Express connectivity. In our motherboard overview we have details on over 55 motherboards to look through.
The Results

Overall, Skylake is not an earth shattering leap in performance. In our IPC testing, with CPUs at 3 GHz, we saw a 5.7% increase in performance over a Haswell processor at the same clockspeed and ~ 25% gains over Sandy Bridge. That 5.7% value masks the fact that between Haswell and Skylake, we have Broadwell, marking a 5.7% increase for a two generation gap.

[ http://images.anandtech.com/doci/9483/01%20-%20Gains%20over%20Sandy_575px.png - Pentru incarcare in pagina (embed) Click aici ]

In our discrete gaming benchmarks, at 3GHz Skylake actually performs worse than Haswell at an equivalent clockspeed, giving up an average of 1.3% performance. We don’t have much from Intel as to analyze the architecture to see why this happens, and it is pretty arguable that it is noticeable, but it is there. Hopefully this is just a teething issue with the new platform.
When we ratchet the CPUs back up to their regular, stock clockspeeds, we see a gap worth discussing. Overall at stock, the i7-6700K is an average 37% faster than Sandy Bridge in CPU benchmarks, 19% faster than the i7-4770K, and 5% faster than the Devil’s Canyon based i7-4790K. Certain benchmarks like HandBrake, Hybrid x265, and Google Octane get substantially bigger gains, suggesting that Skylake’s strengths may lie in fixed function hardware under the hood.
In full speed gaming benchmarks we have some situations that benefit from Skylake (GRID on high end graphics cards) and others that drop (Mordor on GTX 770), but the important aspect to consider is despite Skylake supporting both DDR3L and DDR4 memory, our results show that even with a fast DDR3 kit, a default-speed DDR4 set of memory is still worth upgrading to. On average there’s a small change in performance in favor of the DDR4 (especially in integrated graphics), but DDR4 confers benefits such as more memory per module and lower voltages to aid power consumption

A quick turn to the overclocking situation on Skylake: from our small sample set, most of the CPUs achieved 4.6 GHz when pushing and 4.5 GHz comfortably, including the retail sample that had 4.5 GHz. Speaking to other reviewers, their results match us or even slightly better our own, with one report of a 5.0 GHz gem of a processor. From our testing, Skylake seems to have more of a temperature barrier than a voltage barrier, so increasing the cooling seems to be the task of the day here to get the high frequencies.
With all that, I’m going to make a bold statement.
Sandy Bridge, Your Time Is Up.
A large number of users invested into Intel based platforms during the Core 2 Quad, Nehalem and Sandy Bridge releases. Sandy Bridge was notable because it inferred a large performance gain at stock speeds, and with a good processor anyone could reach 4.7 GHz and even higher using a good high end cooler. With that, Intel has had a problem enticing these users to upgrade because their performance has been constantly matched by Ivy Bridge, Haswell and Broadwell – for every 5% IPC increase from the CPU, an average 200 MHz was lost on the good overclock and they would have to find a good overclocking CPU again. There was no great reason, apart from chipset functionality to upgrade.
That changes with Skylake.
From a clock-to-clock performance perspective, Skylake gives an average ~25% better performance in CPU based benchmarks, and when running both generations of processors at their stock speeds that increase jumps up to 37%. In specific tests, it is even higher.  When you scale up to a 4.5 GHz Skylake against a 4.7 GHz Sandy Bridge, the 4% frequency difference is only a tiny portion of that. There are other added benefits, such as the move to a DDR4 memory topology that has denser memory modules, as well as PCIe storage and even PCIe 3.0 graphics connectivity.
As I said above, Skylake is not necessarily the most ground breaking architecture over Haswell. It affords a 19% CPU performance gain over the i7-4770K and 5% over the i7-4790K. There is a small minor issue with gaming that disappears when you use synthetics, but only to the tune of a couple of percentage points. For that minor hit, the package combo of processor, chipset and DDR4 should be an intrigue in the minds of Sandy Bridge (and older) owners.
What Happens Now?

Next on the list for us is Intel’s Developer Forum in mid-August. Here Intel has said they will present details on their Skylake architecture and it will hopefully shed some further insight into what is going on under the hood with Skylake. We will have a full write up for you after the event.
There is still the rest of the Skylake stack to be released – non overclocking processors, low power processors, and the B/H/Q chipsets too. There is no official date on these except ‘later in the year’. We will also get to these when we have more information.

Hmmmmm, greu de zis. Din ce se vede, Skylake nu e cu mult peste Haswell, la seria I7

10% la aceeasi frecventa, e mai rece, urca mai bine in OC.
Alegerea iti apartine, dar la 15$ diferenta eu nu m-as uita.

Revin cu amanunte.
M-am decis sa mai astept putin, si am sa merg totusi pe Skylake. Cam 1-2 luni, sa vad cum sunt, pareri, review-uri, etc.
Intre timp mi-am luat un GTX 980 Ti Gigabyte Windforce, pana acum totul e in regula, nu am testat inca daca procesorul " sugruma " placa video.
Orice joc am jucat ( folosesc mereu VSync ON ) pe detalii medii + high, am constant 60 fps. Mai mult decat multumit. Pana acum
Dar am o alta problema. O sa deviez putin de la subiect.
E vorba de tv-ul Samsung JU6550 / 40 " pe care-l folosesc ca monitor.
Cum spuneam, e un display superb, imi place din toate punctele de vedere, inclusiv input lag redus, culori, setari, etc etc etc
Cand l-am cumparat acum vreo 2 luni, avea versiunea de software 1210. Imi amintesc ca, pt a putea intra in BIOS / F12 / Safe Mode, etc etc, trebuie sa sting - aprind TV-ul. Altfel aveam mesajul " NO SIGNAL " etc
Pe urma, dupa vreo 2-3 saptamani, a aparut un update. Versiunea 1211. S-a remediat problema. Vedeam Post BIOS, intram in BIOS fara probleme / apasam F12 si imediat imi aparea quick boot menu, s.a.m.d.
Pana aici toate bune si frumoase. Insa, acum 3-4 zile a aparut un nou update, versiunea 1213. Acum nu mai pot intra in BIOS, F12, Safe Mode, etc.Nimic. E vina mea. Nu trebuia sa-i fac update.
Am incercat cu 3 placi video diferite, am pus  fiecare placa in ambele sloturi PCI e, am incercat cu 3-4 cabluri, inclusiv cu unul HDMI -tv si DVI - in placa video, reset BIOS. Nimic.Si nu sunt singurul, pe un alt forum mai sunt cativa cu problema mea, cu tv Samsung 4k / ca monitor.
Unora le merge, altora nu.
Intrebarea mea este urmatoarea : daca le-as explica problema, celor de unde l-am comandat, credeti ca mi l-ar schimba ?
TV-ul are un pixel mort, dar asta nu cred ca e motiv sa cer sa mi-l inlocuiasca. Prefer sa le explic sincer care e problema.
Poate ca, daca mi l-ar schimba, urmatorul tv ar avea tot versiunea 1210
Am sunat la Samsung Service Center si le-am explicat problema, au spus ca totul e de la placa video care transmite semnalul la tv, etc, si au spus ca teoretic nu au ce sa faca. Eventual sa astept un urmator update la software.
Nu pot sa revin la versiunea mai veche de software, asta e. Ori astept ( cateva luni, si poate astept degeaba ) ori vorbesc cu firma de unde l-am comandat online, si i rog sa mi-l schimbe.
Ar mai fi o solutie, dar e riscant, pierd garantia.
Sa intru in Service Menu, si acolo am enjpe mii de optiuni. Nu fac nimic, numai daca sunt 100 % sigur ce anume modific.
Dar in Service Menu exista si "  FACTORY RESET "
Am intrat azi si m-am uitat putin pe acolo.
Oare daca as da FACTORY RESET, ar reveni la versiunea de software 1210, asa cum a fost cand l-am cumparat ??
Aveti vreo idee ?
Ce mi-ati recomanda ?
Multumesc anticipat.
PS : se pare ca sursa mea e depasita de situatie, cu toate ca nu e un jaf de sursa.
E un Corsair TX 650W

Salut! Nu am apucat sa citesc tot topicul, deci nu stiu daca ai apucat sau nu sa-ti cumperi placa de baza insa iti pot spune ca eu am i7 4790k pe un GA-Z97X-UD5H si merge super ok! A trebuit sa scad putin voltajul pe core la 1.788v  ca era cam mare( ceva obisnuit la toate placile gigabyte)! Cu acest voltaj a stat sistemul meu sub stres prime95 toata noaptea fara probleme! Am preferat aceasta placa de baza ca are 8 conectori sata din care 2 sata express si 2 placi LAN! Initial am vrut sa merg pe varianta gaming 5 insa are doar 6 sata iar UD5H are cam tot ce are varianta gaming si ceva in plus!
Am facut hackintosh cu mavericks si cu yosemite! Cum eram nou in domeniu  hackintosh a fost ceva bataie de cap la inceput pana am invatat tot insa la urma parca era destul de simplu! Acum am renuntat la mac os pentru ca intr-un final dupa cateva luni de teste eu prefer tot windows!

EMP83, on 15 august 2015 - 20:24, said:

Da, cum spuneam si ieri, am sa mai astept vreo luna - doua. Te cred ca esti multumit de i7 4790k.
O sa ma uit la cateva review-uri / teste / si o sa ma decid intre Skylake sau  i7 4790k.
Dar deocamdata caut solutii la ce scriam aseara, legat de monitor. E foarte enervant ca nu pot accesa BIOS-ul / F12 / Safe Mode, etc.
Azi am incercat sa intru in BIOS ( am un monitor secundar, doar pana rezolv problema )  am pus pe PCI, la Init First Display, dar tot nu merge.

Revin cu o intrebare : vreau sa-mi schimb sursa, deja incepe sa-mi faca probleme.
Ieri, am stins pc-ul si am oprit sursa din butonul care e pe sursa. Cand am pornit butonul, mi-a cazut siguranta de la tabloul de curent din apartament
Lucrul asta mi s-a mai intamplat odata, exact la fel, atunci aveam GTX970-ul.
M-am uitat la cateva modele, si as vrea sa va intreb ce parere aveti de asta
Corsair CX Series Modular CX750M 750W ATX 2.3 - 95 euro
Credeti ca e okay ?

Va rog sa-mi dati un sfat, acum 10 minute iar mi s-a intamplat. Am dat restart la pc si am iesit din camera pt. 10 minute, cand am revenit era oprit pc-ul.
Am incercat sa-l pornesc, nimic. Pe urma am oprit butonul care e pe sursa, l-am lasat vreo 10 secunde, l-am pornit si acum merge.
Eu cred ca sursa ori da semne de oboseala, ori e prea slaba ( n-as crede, dar nu am alta explicatie ) pt GTX 980 Ti
Inca un amanunt : acum 2 minute era oprit PC-ul, l-am pornit, apoi dupa ce porneste, nu ajunge pana la Windows, isi da restart, pe urma porneste dar nu intra in Windows....
Credeti ca e sursa de vina, ori e vreo problema cu placa video ?

Edited by eduard_w, 17 August 2015 - 14:10.

N-are nimeni o idee ??

poate fi sursa sau ceva supratensiune pe retea ,  cat despre CX-ul la care te gandesti mai bine mergi pe RM sau HX daca nu ai buget de AX/AXi,  mai nou si HX are mod hibrid la ventilator

Am vrut sa comand EVGA Super Nova G2, dar nu o au in stoc...
As merge pe Enermax Platimax 750W
http://www.expertrev...max-750w-review
Dar nu sunt hotarat. Nu vreau sa risc sa-mi " prajesc " vreo piesa din calculator.
Oricum, nu am sa astept pana intra in stoc EVGA-ul.
Ce optiuni as mai avea ?
Buget aprox : 140 euro

Corsair RM 650i varianta noua cu  Corsair Link Digital (precum gama de top AXi), Seasonic G series 650w sau X series pt ~100 ron in plus

prefer totuși o sursă de 750 w
