which CPU will not bottleneck GTX 1080

[Alijericho]

As title says I need a CPU that will run my GPU to 99% load.
Currently my GPU runs 70-90%,

Secondly, I saw a video where two CPUs were compared. Both ran GPU at 99% usage/load, but the difference in frames was 20-30 fps. How is that possible when both are utilizing GPU to 99%?

My PC Specs:-
CPU Intel 4790
GTX 1080
h97 gigabyte
8 GB Kingston rams
860i corsair

Two CPUs might easily have different cores, architecture, bandwidth, frequency, and so on.

As for a replacement, if you're after something as a straight swap, with no change in mobo (i.e. same socket), your most likely option is the 4790K, which will be about 10-15% on your current CPU. Whether it's enough to get your GPU to 99% is another thing. Price and availability will decide things, I think.

If you go to CPU Bench and see your CPU, it's around 10K scores - https://www.cpubenchmark.net/high_end_cpus.html

The 4790K is around 11K, and I estimate a CPU in the 13K range to get the most from your GPU. I doubt there's one at a good price for a socket 1150 mobo. So then you might consider a new mobo and CPU, but that might / will involve new RAM, a new OS install etc.

Where the bottleneck is depends on the game. EVERY system has a bottleneck somewhere and it is typically the CPU at least at lower resolutions. If you are at 1080p the CPU will nearly always be the issue. At 1440p and higher the GPU will be, unless you are seeing real performance issues just run it as-is. As far as youtube videos, don't believe everything you see, many folks aren't using comparable settings so it makes such shootouts meaningless.

Im at ultra wide 2560x1080, I know the CPU is the bottleneck. I am looking at 4790K for upgrade.
Do you mind sharing your Heaven Bench score as u got a 4790K and GTX 1080. mine is around 3000

Thanks for great answer. It addressed my question fairly.
If only I could see real time comparison of 4790K vs 8600/8700 so I can be sure that the expensive upgrade would be worth the trouble. Best $ to performance gain as they say. Could you please direct me to heaven scores of different CPUs with gtx1080.

It's not worth the money, unless you got money to burn!

I'm on the i5 unfortunately, that OC in my sig is up to 4.6 now all cores though xD. I'm looking at the i7 4790k as well tbh. I can get one new for about $500cdn right now, hoping some extra threads can help run the background crap I do when gaming and it's cheaper and easier than redoing the entire system.

Alijericho Could you please name the game or games where you're seeing the CPU bottleneck?

Well, I'm running Heaven bench and it's running GPU load 99% almost 9/10 of the time. It usage seems better than last time I tested it. My score still is 3000. I've seen others posting 3200. My GPU is OC to Max possible 2100mhz. The games I'm talking about let's say Dying Light without Vsync cap run 83% giving 116fps. CPU all cores fluctuate 70-88%.
