Area-51 R2, bottleneck, i7-5820K, Asus Radeon 6600 8GB Dual
Hello, I have the Area-51 R2 desktop and I want to change the GPU. I want to know about the bottleneck of my CPU (Intel Core i7 5820k) with the Asus Radeon 6600 8GB DDR6 Dual and what problems I'm going to have in gaming?

there are different theories out there, some saying bottleneck depends on resolution some does not. I am posting gpucheck calculator to show you the average benchmark fps you would expect based on cpu and gpu match. the calculator appears to show a fixed cpu impact on fps regardless of resolution, which is -20% in this case. it is saying the cpu is slower than gpu and will pull down fps across all resolutions. use it for reference only for whatever it is worth.

It depends on the resolution but with that processor you are at 20% bottleneck on the CPU, with a Radeon RX 6600 XT.
It does not cause a direct problem, but you will not be fully utilizing the Video Card with that CPU.

maybe less than 20% bottleneck. rx 6600 is 23% slower than rx 6600xt.
20% if you pair i7-5820k w Radeon rx6600 xt,

What I'm saying is that the bottleneck is gonna give me problems in a 144Hz monitor and not in a 60Hz monitor. Is that correct? Also thank you very much for the help : )

if you want to push for 144 fps, try a lower resolution and lower settings for cpu/gpu combination.

A friend told me that if I have a 144MHz monitor I'm going to have problems with fps. Is this correct ?

I think you are confusing things. While the bottleneck has an effect on the FPS, the main concern is the reduced performance of the card.
If you invest money in a card, only to have it perform 20% slower than it should, you could get the same performance and FPS out of a cheaper card.
It's highly dependent on the resolution you game on, and we don't know what resolution your monitor is so it's hard to provide an accurate number.

There are 2 bottlenecks possible: CPU or GPU.
With higher resolutions the bottleneck shifts from the CPU to the GPU. That is why review sites test new CPU's at 1080P or less and GPU's at 4K resolutions.
Anything 5% or less is considered no issue and a good match. Besides resolution it also depends on the game itself, as some games are more CPU intensive while others more GPU intensive.
In the end you have to take these sites with a slight grain of salt because many factors will affect your overall CPU and GPU performance, like thermals and clock frequencies, just to name a few.
