i5 or i7 for gaming?

[Shinpool]

I read in several forums that i5 is more than enough for gaming. can someone explain why? is it true that using i7 for gaming is a waste of money? i am saving for a gaming pc, i can start buying the parts this november, but i am not entirely sure about my build.
cpu i7-6700
mobo asus b150 pro gaming aura or msi z170 A gaming M3
gpu msi gtx1070 duke
hdd seagate 2T
psu Tt smart 550W
ram fury ddr4 16g
cpu fan deep cool 400 or cooler master hyper 212x

any thoughts? the mobo depends on the cpu. not really sure whether i5 or i7.

^ You need to look at Gamegpu.ru CPU tests. It's true that most of the time the i5 equivalent does fine, but the recent trend is i7's getting better and multithreading capabilities will be improved in real DX12/Vulkan games (though not today's half assed ones).

While it is true that an i7 6700k beats an i5 6600k in benchmarks, the difference in actual games is so minuscule (1-2 fps) that it isn't worth the extra $100

I was speaking of games, not benchmarks.

In conclusion: get an i5 if you are doing just gaming and not video editing or 3D rendering etc.

Game benchmarks. Watch the whole video

okay, i5 it is. one more thing, how about zotac gpu, is it good?

[_I_]

zotac is ok

but ditch the thermaltek power supply
get a better quality 80+ bronze 550+w

do i really need the 550W? i just calculate the watt that i need in outervision psu calculator, it says i need 419W-ish in total, so i think 500W is more than enough

450 will be enough, but 550 gives more headroom if you add more drives, fans ect..

This video is rubbish. Unless the cpu and gpu load percentages are shown it doesn't demonstrate anything. From the framerates achieved it is clear that the 980ti is limiting the performance of the cpu's. So no conclusion about which cpu is better is possible.

68fps for Witcher 3 with an overclocked 6700k is hopeless. My i7-2600 and gtx970 can do close to that. A stock 6700k on a fast gpu will achieve over 100fps at 1080p.

If you find a specific model that you really like and it is 500 without having a 550 or 600 variant at almost same price, you can take it. IMHO 500 is kinda stretch.

I'd not say completely rubbish -- but certainly any test results need proper interpretation and understanding. The conclusion is quite firm for anyone having GPU in that range. And hopefully you dare not call such rigs "not gaming" ;-)

Sure, you may add more and more powerful GPUs and mix up some settings to show more than the 1 fps diff just to prove some point, but then we're likely well above the sensible fps range that is needed for a game. And even then you have the gfx fine tune options.

OTOH certainly when you know the composition of your rig, the monitor, desired resolution, it is best to look at tests made with that and chose the rest of the components accordingly.

I would get the i7.
Then again I would eventually get the i7 6800K instead of the i7 6700K too. But that make the most sense for those who for whatever reason take a motherboard which was already expensive and close to priced as an X99 motherboard anyway.

As for what others have said about more games demanding i7s I don't know if that make sense, maybe because processor advantages have been happen so slowly. Anyway Kaby Lake will likely have been released by then or will be around then and have some more improvement. I don't know which models will be getting the eDRAM but at-least with Broadwell the to be fair only two desktop models released the i5 5675C and the i7 5775C both got it. The Broadwell processors had good advantages of the eDRAM so I assume Kaby lake will too.

Then again over-clocked to the same speed the difference of course is smaller (to the level where the 6700K may not be worth it and you'd be better off with the 6600K.)

In that case maybe you don't feel it's worth it for hyper-threading alone? In the case of the 6800K it would be another two cores though.

[Aliquis Freedom & Ethnopluralism]

TDP in case of AMD is a theoretical maximum whereas for Intel and Nvidia is a more likely maximum.

At-least sometimes some components has drawn more than their labeled maximum at some times, the calculator may use an average draw at full load whereas in a short time-frame the maximum draw may be higher but averaging out lower over more time.

I don't know if the goal of the calculator is to suggest a PSU size or tell how much power the system will use because the two will not necessarily be the same. It's not like the price difference of 420 vs 500 vs 550 vs 600 watt PSU is all that massive plus the PSU is less efficient at max (and low (but then the power usage is low anyway)) load which may make the over-powered PSU more power efficient and hence consuming less power which cost less money which may help cover the difference in price.

Do you really think an i5 6600k is going to bottleneck ANYTHING? And don't be ridiculous. I have an overclocked gtx 970 and I have to turn down foliage and shadows just to keep it at 60fps. With an i7 6700

Screenshot links on the page below of my i7-2600 and gtx970 playing Witcher3 (ultra settings minus hw) at 1080p. Since the shots were taken I have installed high-res textures and the rig still scores 50-60fps. I did optimize the buffering config and my i7 runs at 4.3GHz, so that might explain a few things.

Regarding whether or not I think a 6600k is going to bottleneck anything, I only play rpg's so I don't know.
