No way that your i5-4670K bottlenecks your gpu... you can always overclock it and see if there is any change. I am using i5- 3570k and don't have a bottleneck... Using 1440p monitor.

Recently I received my gtx 1080 FTW, of course very happy with that. Thing is though I feel like the combination of the lower resolution of 1080p and high frame rates causes my CPU to bottleneck the GPU in certain games/areas of games. Example: GTA 5 benchmark (very high settings), CPU runs 80-95% all the time while the GPU hangs around 65-80%. More specific example: The Witcher 3 (high, no hairworks) walking around Novigrad 'only' gives 60-80 FPS, with the GPU not being under full load. Battlefield 4 only 120 fps, not even passing the 65% GPU load mark...

I am currently playing on a BenQ XL2420G 144hz G-sync panel btw and my i5-4670k runs @ 4.4 ghz.

It's 100% your CPU. Thank you for testing; if the GPU is not loaded at 90+%, it's being bottlenecked. :(
 
4 threads aren't enough for 144Hz on CPU-intensive games like GTA V and BF4. :( I know it's crazy, but after you push 100FPS, your CPU becomes far more important.

Intel Skylake: Core i7 6700K review (from Digital Foundry)

I have the FTW 1080 (thank you EVGA), but an old CPU, I7980X. Of course this processor does have 6 cores and 12 threads. Futuremark has a hardware channel where it ranks processors as at July, 2016. Looking at that, my I7980x physics score is 8410 and the I5 - 4670K is scoring lower at 6370.
 
For me, Tomb Raider (DX12) maxed 1080P graphics, the GPU is at 99% so no CPU bottleneck. I just ran Witcher 3, again 1080P maxed graphics, no hairworks. GPU usage is 95%, core clocking at 1949 and FPS at that point was 167. So I'm not seeing a bottleneck with this old CPU. Might have something to do with the 6 cores, 12 threads. If you want to see a screenshot of the Witcher 3 data, it's on the Windows 10 forum, gaming/what games are you playing now.
 
Don't have the numbers for BF4. I'm using the Precision XOC (which I like) for the OSD which is giving these numbers but it doesn't seem to work for me in BF4.
 
Loving this EVGA FTW 1080. Previously had two Asus 770 Keplers is SLI. Struggled to maintain 60FPS in Doom 2016 at low settings. Now I have graphics maxed out at 1080P, FPS hit 200, often around the 150 mark and I believe the lowest FPS I saw in Doom was 110.

Ikjadoon, add spaces in the URL and it will go through but I found them from what you linked.
 
 
 
 
 
 

Oh! Thank you. I appreciate it. :D

There's something wrong here. How can you be getting 167FPS on Witcher 3 with a GTX 1080? Not a single review of the GTX 1080 with The Witcher 3 @ Ultra 1080p shows anything close 167 FPS.

Are you testing in a "busy" part of the game? I don't play Witcher 3, but 167FPS sustained is better than GTX 1080 SLI.
 
Also, see the Eurogamer review above. The Witcher 3 sees a 25% FPS increase going from the i5-2500K to the i5-6600K. I'm not saying you didn't see 167FPS, not at all. Just that you may not be testing the same rigorous environment every review publication uses.

No, that 167 is NOT  an average FPS. I loaded the game where I left off (second time around) to see what the FTW was doing in that game.You can see it on the screen shot I posted in the Windows 10 forum. The question was whether lower resolution (ie 1080P) where you would expect high frame rates is being bottle necked by older CPU's, as the poster was only seeing 65%-80% GPU usage. What I'm saying is at least with the I7980X (about 6 years old), the FTW is at 95% usage and achieves very high framerates. On Tomb Raider (1080P, DX12, maxed graphics, hair works on) the GPU is at 99%. Point is at least this I7980X processor doesn't seem to be bottlenecking the FTW at 1080P. So perhaps with his processor there is a CPU bottle neck, given the lower GPU usage in the same game, Witcher 3..

sorry to break it to you but yes a 4670k most certainly holds back a 1080 in some cases especially for the OP at just 1080p trying to get 144 fps. I tested my pc in games for a week with HT off, which makes it essentially a 4670k, and several games fully pegged the cpu at times. I even got some hitching in cpu limited areas of some games and in a few cases could also not even maintain 60 fps. anyone thinking their i5 lets them get full potential of a 1080 is deluding themselves.
