I'd never heard of them before, had to look them up. After reading a bit I'm not convinced that it's going to be helpful to you.
What are the CPU c-states? How to check and monitor the CPU c-state usage in Linux per CPU and core? - GoLinuxHub
The problem you're having isn't related to intel processors, if it was literally millions of users would have complained by now.
Using the same logic, the problem you're having isn't directly caused by the nVidia card, if it was it'd be all over the news and they'd be going out of business. Plenty of people have the same card as you, including me, and don't have the same problem.
There's a slim chance that the problem is caused by a fault in your motherboard but that's pretty unlikely these days. The best way to test that is to try a different graphic card and see if the problem persists.
The problem has nought to do with Linux kernels, it if did we'd all have similar experiences. That means it's either the driver you're using, or the implementation of that driver. Or something else within the specific Linux distro you're using.
That pretty much only leaves two options:
Try a driver that hasn't been "fixed" by your distro's development team. ie: Not From The Repository.
Try a different distro.
