PC bottleneck maybe cpu? Suggestions needed

[MissAuroraKitty]

So I have posted in another section but I think here might be better, so I've had my current PC for 5 years. But as of recentently alot of games has been boggling my current pc down on cpu side, games that mainly vrchat and rust and some space engineers, so my cpu sits at 70-90% minimal on most cores, also I've noticed my cpu loads up with my internet usage. I've reinstalled windows, downscale my vr headset resolution and such to no success, I have a 1200 watt psu and hybrid 2080ti so that both things I dpubt would be causing issues. So any suggestions to cpu upgrade or such in general or setting fixes would be awesome!

anyone?

If you are using a 5930k then you will have a bottleneck problem.

 

The 5930k has about the same IPC as an i7 4770k or a R 3 2200G and that is not suitably at all for a 2080 ti.

 

Even my i7 8700k that ran perfectly with a GTX 1080 ti had issues with a RTX 2080 ti but my i7 8680k that is a 5ghz chip did not.

 

For picking a CPU for a RTX 2080 ti I use Cinebench R15 single core test and I consider any CPU with a score of less than 216 unsuitable for a 2080 ti.

 

So for Ryzen a R9 3900X or a R9 3950X. For Intel an i9 9900k or better.

 

I play building games like Space Engineers and modding games like Skyrim and Fallout 4 and high IPC and frequency is a must if you like to push it and stay smooth.

@jones177 can a 3700x work?

It depends on what your 2080 ti runs at. 

 

I tested between a my two gaming computers. At the time they used the same motherboard ram and SSD so the only difference was the CPUs frequency and the cooling solution of the 2080 tis

 

One is an i7 8700k at 4.7ghz all cores with an EVGA FTW3 Ultra 2080 ti running at 2040mhz average overclocked.

The other is a i7 8086k at 5ghz on all cores with an EVGA XC 2080 ti running at 1950mhz average overclocked.

 

The computer with the 5ghz CPU won every test even though the 2080 ti was slower and cost $300 less. 

It made the FTW3 Ultra pointless.

 

I only noticed the difference in performance because I have 2 gaming computers.

When they were both were running EVGA 1080 ti SC2s the difference between them was 3 to 5 frames in games and benches. The 1080 tis made the 5ghz CPU pointless.  

 

I replaces the i7 8700k with another i7 8086k and now the FTW3 Ultra always wins.

 

At hybrid temps and good silicon your 2080 ti should run between 2085mhz and 2115mhz overclocked. If you want all the performance get an i9 9900k and overclock it to 5ghz on laa cores or more. 

 

If you don't mind losing a few frames get the R 3700x. The difference in gameplay does not exist in vanilla games.

In building and heavily modded games it can mean the difference between smooth and stutter if taken to the limit.
