RTX 3090 (zotac) 500 cad - 358.62 usd
Rx 7800 xt (founders) 600 cad - 430.35 usd
and why?
both used (note this is the cheapest rn and it wont go down on facebook marketplace)
better ray tracing, better frame gen (Dlss) and whole lotta fuckin vram which is pretty much needed for these newer games especially if youre gaming in 1440/4k
depends on your other parts but imo just get a 850-1000 watt. im rocking the rm850x by corsair and no problems. just find whatevers cheapest and search on reddit if its gonna blow your house up or not
