I'm also having a 3950x for Rust work and it has been the fastest CPU I've ever used. It just flies every day and makes rust compilation times not an issue anymore.

That means, I really don't know do I want to have the trouble of finding the 5950x and the work of replacing the CPU. I really don't feel like I need more CPU power at this point.

But replacing my 2080ti with a new fast Radeon, that would be something...
