NV Link 2080TIS

I plan on going real high end workstation but if do plan on doing dual systems using my 7700K as my secondary for streaming/recording. For my main system I wanted to go with a 7960X will my dual 2080TIs bottleneck the CPU? If not what CPU could I go with instead of the 7960X since it’s not really for gaming but not be bottlenecked.

it depends on the resolution you play and the game you play, say you play 1080p ultra settings your 2080ti will be bottleneck by the cpu (i.e. GPU load is under 50% and CPU load is 100% this is highly improbbable), increase the resolution to 1440p and you put more load on the GPU's and you get identical frame rate, but your GPU load will be 90%, increase it to 4k and you GPU load goes as high as 100% and you CPU load will drop to 50%, but it is not always the case with high end multi core cpu's because it is not the core count that metters in most of the games but the IPC and clock speed. Your CPU will be bottleneck (ether by only if you play a really multithreaded game at the lowest resolution possible. Add rtx features to the equasion and high resolution and you will never see CPU bottleneck

So essentially I don’t want my CPU to be at 100% and I don’t want my GPU to be at 100%. I do plan on wanting to play 4K max settings.

Cpu and gpu are not combustion engines in the car, in case of the engine you want to run it at max efficiency (max torque) and get max milage. 

There is no moving parts in the cpu and max efficiency of cpu and gpu is 100% load. So in the ideal world you want your hardware to run at 100% load and at safe temp.

For example you got a celeron or pentium cpu and a gtx 1030 and both of them run at near 100% load and deliver 40fps. That means the system is crap but it is as efficient as it can get and balanced. You throw away you 1030 and put a rtx 2080ti. You still get your 40fps but your all mighty 2080ti is running at 10% load

next you change your cpu to 9900k but put back you 1030. In this case cpu can produce 200 frames, but you 1030 can render same 40fps. And your cpu is running at 10% load.

You rig can run as fast as your slowest component.

with 7960x and dual rtx2080ti you will get a monitor bottleneck unless you will not change it to 4k120hz adaptive sinc.
