atm i have an fx-8350 @4.0ghz and an r9 390x 8gb, it can run everything i play at 1080p, max settings, 60+fps and its beautiful, but i wanna go BIG and get a 4k monitor. my question is what would be the best way to get my rig to 4k without losing the high settings and fps.... could my 8350 handle a second r9 390x? (yes i can definitely crossfire with my current build) and would that allow me 4k high settings decent fps? or do i have to sell my pc to the devil and go for broke with a new i5/i7 rig?
