Why are you upgrading?: I want to be able to run 4k, max settings, ray tracing and all the fancy new features/tools/cpu or gpu intensive mods at ideally 90fps, or more, for current and future games at least 3 years into the future.
If by some chance I end up talking myself into doing a massive overhaul of my system, then I'd be also looking into liquid cooling the cpu only, as well.
Games, programs or workloads that it will be used for: Immersive, Atmospheric FPS/RPG games. God Of War, Cyberpunk 2077, Starfield, Remnant 2
Budget (including currency): Flexible, but would prefer to not to go above 2000 USD at most. Doesn't mean I can't, though.
Country: US
Other details
Monitors: MY main monitor is an LG C2 Series 42-Inch Class OLED evo with an Acer Predator XB271HU bmiprz 27" WQHD (2560x1440) as a side monitor. It causes some minor issues using two displays at different resolutions, but its tolerable, I don't plan on upgrading.

EDIT: We can skip the suggestions for hardware not listed in the post, like case for example. I already have it and am happy with it, unless there is a compelling reason to change, like, powersupply not capable enough or something
EDIT 2: Thanks for the responses, the general suggestion seems to be to upgrade to the AMD Ryzen 7 7800X3D 4.2 GHz 8-Core Processor . That'll require a lot more research than I had anticipated, but I'll start working on that soon.
