Ok so i already have a r9 390 in my system and i want to setup crossfire. Can ( or should) i set up a r9 390x for better perfomance or should i simply stick another r9 390?
well i have a i7-4790k. Im running at 1080p but would like to uograde to 1440p in the future. As for my power supply, ill change it once i get the new card, since its only 650n watts.
R9 390 seems to be plenty fine to 1440p resolutions. Can you add another for CF? Absoluty yes, but you will require a new psu, at least 850W and maybe 1000W.
