I upgraded my system memory from 16GB to 32GB. I don't think I needed it, but now I'm able to run Doom Eternal, Assassins' Creed Valhalla, android simulator, and about 50 chrome tabs all at once. I managed to get to 90% utilization.
Finally decided to retire the geforce 1080ti and got a geforce 4070ti. The sizes of these things just keep getting more and more ridiculous Pushes right up to my radiator but whatever.. https://pcpartpicker.com/list/3VCFNc
I've noticed the 7900 XTX is actually in stock now and then on newegg, but the Nitro that I would want is always price gouged at ~$1500.
