yeah, gotta underclock it... and for that i gotta install winblows... might be a firmware patch anyway...

from what i'm reading, actually the 7800XT is competitive with the 4070 at the same power draw, but cheaper, so it's a lot of extra power (30W) for like 5% more performance - that top end costs 2x the watts for the performance, and lowering this will make it more stable probably, and run a bit cooler

i'm still getting a new PSU anyhow... i'm pretty sure once you have a PSU with half melted components in it it's gonna be a bit shaky in the top end of its rating forevermore
