I am just about to make a major PC [upgrade] purchase. I came across this PC Version Of 'Metal Gear Solid V: The Phantom Pain' Out On Same Day As Consoles article while browsing inside tom's hardware. The recommended specs include a i7-4790 processor which is incredible because its so brand new. It got me thinking will a 6700K become recommended hardware for games within 2 years' time?

I was decided about the 6700K +GTX970. [http://pcpartpicker.com/user/ObelixThe/saved/#view=rCGzK8]

Should I rather opt for a 5820K and OC it to 4.2+ Ghz? [http://pcpartpicker.com/user/ObelixThe/saved/#view=4tPWGX]

If I can OC the i7-5820K to a stock 6700K's clock speed then will it be better than the 6700K?

I am more inclined towards the Skylake because it is newer and slightly cheaper than a Haswell-Extreme build.

However, I really enjoy Strategy games with massive maps and 8 [or more] players with huge numbers of units.

So I am wondering if I can get some expert advice whether or not a overclocked 6-Core 5820K would be superior to a stock 6700K?

For the GPU I am probably buying either the GTX 970 or the R9 390X.
For the PSU I am considering between the CM V750S and V850 models.
I really like the Inwin Case so that's what I am getting.
For motherboard if I buy X99 I will get the Asus x99-A. For skylake I'll get the Gigabyte Gaming7.
For RAM 16GB G.Skill DDR4-3000 [8GB x2 or 4Gb x4].
I am kinda scared of the kind of CLC failures I read about so I will stick with a cheap aircooler like the 212X or 412 slim.

Any and all suggestions, advice are most welcome and appreciated.

Other than the architecture the only thing the 6700 ahs over the 4920k is the clock speed. With the 5820k overclocked to 4.2 ghz, that should easily be better than the 6700.

Technically speaking the 6700 isn't at the same level as the 5820k, its a lower i7, the only difference is of course, the newer architecture. Even with that though, the 5820k should perform better even without the overclock.

Hi. Thanks for your input.

So you say that the 6700K is a weaker than the 5820K? Yeah, that's what I thought too because it has 2C/4T less.

I just came across a tutorial/article Skylake: Should you Upgrade? by TechyInAZ.

It answered many questions I had.

Although all the other threads I read stated that the 4790K/6700K are superior to 5820K.

So I am really confused as to who is right. For me its a big decision dropping almost $1800 on a PC. So I want to be sure the CPU will be good enough for at least next 5 years gaming.

I will of course upgrade the gpu that's why I am into the gtx970 because I game on a 1080p resolution.

The 6700 is NOT superior to the 5820k. That's for sure. As for the 4790k, I'd still say the 5820k is better, more cache memory and cores (then it has hyperthreading, giving it 6 extra virtual cores), and the generation is newer. WIth the overclock it should be far superior to the 6700 and 4790k. You said you wanted it for the next 5 years, so as games become more advanced and start requiring more cores and power the 5820k will then truly shine. 12 total cores........
You can take a look at this if you want for the specs: http://www.cpu-world.com/Compare/590/Intel_Core_i7_i7-4790K_vs_Intel_Core_i7_i7-5820K.html

I own the 5820k (mine is overclocked at 4.5ghz instead of 4.2) and i will promise you if you get that cpu you will absolutely love it.

I have a very hard time putting to much stress on this thing, but i mostly game or stream so it makes sense

I looked into it a bit more, the only reason the 4790k is "better" is because of the value, but in terms of the performance the 5820k with the OC should be far superior. If it's performance you want, I'd stay with the 5820k.

Well, please allow me to throw a different opinion at you.

I'd say go with skylake.

Look at it this way, the gaming performance will be fantastic. You are going with a platform that has a future, maybe something really interesting will come up in the next couple of years for that socket. You get to bank 500 dollars towards a new gpu in a few years. You could even buy a second for SLI when they come down in price, or you never know what can be had in 2-3 years time.

That i5 isn't very powerful in comparison to the 5820k though....... He wants to run a game with a recommended requirement of an i7 4970............The i5 you suggest is less powerful than the 4790.......

Ok, lets get some stuff straight here.

The listed requirements for games dont mean anything, and should be taken with a grain of salt.

Secondly, skylake is a waste of money, its performs pretty much the same as haswell refresh/haswell e.

A 5820k is better than any skylake cpu because of the extra cores, the ipc is on skylake is only about 5% better, which is not noticeable in games, in fact some benchmarks have showed that skylake performs worse in some games.

Question is, do you need the extra 2 cores. If your just gaming, no. If your doing editing/multiple programs, yes then its worth it.

The 5820k system would be more expensive than skylake, while a z97 platform would be cheaper than skylake and x99 and offer gaming performance near equal to skylake.

... yes, buit only so far... the socket was just released, try not to write that off.

OP as for gaming, no games advantage is to be had with more threads r more than 4 cores for that matter games still need clockspeed, clock is king so to say. Take a 5820 for example, leave it at stock, overclock te 6600 k using the same gpu and you see plainly the results reflect what I am stating.

i7 offers no tangible advantage for gaming, even streaming or recording games the impact on the game will be miniimal.

After a quick review I do find that the 980 ti is a pretty reasonable price.and the 980 is priced poorly, but 180 vucks isn't exactly a small amount. The model I suggest can take a massive overclock if you are so inclined. If you want to game seriously spend less on the cpu and more on the gpu. The performance in gaming follows the gpu not the cpu.

A slightly faster chip with room to upgrade, Why buy into a socket with no planned innovation? Sure the older setup is more affordable but what upgrade path will the OP take? 1151 is just released with at least another 2-3 years of potential upgrades, I see no real reason to buy in at a slightly lower price.

I was being conservative to allow for leftover cash for a future gpu upgrade but let;s just go ahead and commit to a best setup

add 100 for the i7 6700k over the 6600k

add 180 for an upgrade to the 980ti

60 more to upgrade to 16 gb of ram

this offers a far superior gaming experience vs a i7 5820 and a gtx 970

and in reality.... the upgrade to the 6700k offers next to 0 gaming performance over the i6 aside from the clock speed which can be overcome with a very simple and fairly moderate overclock.

All that being said, there is still potential for further cpu upgrades over the next few years, the other two platforms not so much except the 8 core chip on the 2011 v3 option, but I wouldn't count on that costing less than it does now until it becomes obsolete.

I was all for saying haswell was good enough as it really is except that there is nowhere to go once you have the 4790k where as the 1151 is fairly new and will be able to offer more.

This is my Skylake Build @PcPartPicker.

I typically keep a PC for 5-6 years. The GPU I will upgrade after about 2-3 years. Then sell off the whole setup and buy anew.

That's why I am inclined towards the i7-6700K (instead of the i5-6600K) because besides gaming, I also want my system to be responsive for the full 6 years.

However, the i7-5820K (seems to me) to be more future (the next 6 years from now) proof as a gaming processor.

There are quite a few game titles which already require a Intel QuadCore CPU such as FarCry4, Battlefield4, Battlefield Hardline, AC: Unity, MSGV just to name the few I know of.

@Spentshells Can you say with certainty that in 4 years' time games will not use more than 4 cores? If you can, then I would rather get the 6700K build because it is cheaper than a PC with the Haswell-E 5820K.

@spentshells & @LookItsRain

Both of yous are master/authority/experts and you are offering different suggestions.

That's why I am so confused, cuz both of yous can't be right, right?

For 50 dollars more, you get 2 more cores, and 4 threads.

For 100 dollars less than skylake, you get 4 cores 8 threads, same as the 6700k, with a roughly 5-10% performance loss across games and applications.

http://www.anandtech.com/show/9483/intel-skylake-review-6700k-6600k-ddr4-ddr3-ipc-6th-generation/22
http://www.anandtech.com/bench/product/1543?vs=1260

My point is, that 5-10% extra performance from skylake is irrelevant, we still have cpus from 2011, like sandy bridge, that can still power sli 980 setups and similar without a bottleneck, and those are 20-30% behind haswell. The only real advantage z170 has over z97 is usb 3.0 ports and pcie lanes, thats it. By time your ready to upgrade, there will be a new socket anyways, so skylake isnt going to last any longer than haswell will.

Also, like ive stated before, the listed requirements for games are pretty much 100% overstated or just random upper tier hardware, an example is the shadow of mordor requirements, which state an i7 3770 or an 8350, the 8350 is a few tiers down from the i7. The same goes for gpus it recommends, it states it recommends a 660 or a 7950/r9 280, which the 7850/r9 280 is much faster.

Further edit, i doubt intel will release anything better than the 6700k on 1151 other than another die shrink, which will only bring in another 5% performance. Just like broadwell, if you bought a 4770k, you are not going to upgrade to a i7 5775c, there has not been a serious cpu upgrade without a socket change for years.

I really like the GTX 980 Ti, but am reluctant to spend so much on a GPU that's gonna be outdated within 2 years (like the GTX 780 Ti).

Anyways I need some time to process your input so I haven't decided yet.

I will buy within the next 2 weeks from the moment I am typing this post.

If I go the Haswell-E route the GPU will most probably be the GTX970.
If I buy Skylake (i7-6700K), then I will try to fit the GTX980 Ti in my budget by making some concessions.


Thank you both for your input. Really, cleared up a few questions.

I was all for promoting the new hardware, but what was presented there would be immensely enjoyable regardless of which you choose.

As for using more than 4 cores? It's extremely unlikely, that being said the 6700k can process 8 threads 4 cores and 4 virtual cores. As for my first build with the 6600k I would look to that, it leaves you with money in the event that you want to upgrade the cpu to a 6700k and a gtx 980 in the future.

I'd agree (if I had ever used a Core i cpu 😉 )

Been reading the reviews and benchmarks on 6700K & 5820K. X99 is an old chip and no newer CPUs for it. I'd feel assured if at least it'd support the Skylake-E. Whereas, there could be better CPUs for the LGA1151. Plus, going with Skylake I can just barely fit the GTX 980 Ti [MSI Twin Frozr V or, Gigabyte G1 Gaming] in my budget. That should be good for at least 3 years' gaming at Ultra settings, right? It also fits in my plan to switch to a 4K TV I am planning to buy when prices become more reasonable.

Skylake e, like haswell e will be on a different socket. Buying a 6700k over a 4790k is honestly a waste of money, you will get almost the same fps out of a 4790k for less money.
