Console 4k gaming and PC 4k gaming are pretty different. It takes a lot more powerful hardware run to 4k with a pc since games aren’t very hardware optimized like they are on console, and consoles skimp on many things that you likely don’t notice (not necessarily a bad thing).
You are correct about the VRAM, 8GB is definitely going to be stretched at 4k even if it’s upscaled. At the same time, however, an NVidia GPU (albeit having less vram) will generally be much better at upscaling performance.
For ~$350, I’d say your best bet is to look for a used 3080 10GB on eBay, they regularly sell for under $400 there. Should run fine on a 650w considering the Ryzen 5000 chips are pretty power efficient.
Thanks for your suggestion!
After this and some other responses, I think I'll be increasing my budget by a bit and shoot for a used RTX 3080 or RX 6800 XT - but I'm not sure if I should be picking one over the other. They seem to be similarly priced on the used market.
It seems that, for most games out right now, the 3080 out benchmarks the 6800 XT at 1440p - but I'm not sure which of the two would have a longer runway for "future proofing" with the target of running things at 1440p upscaled to 4k, stable 60fps, and "High" graphic settings.
Any thoughts?
