I am having a huge problem trying to decide which one of these cards will be best for me, I like to play arma 3 and bf4, I have a pretty low end APU: a8 6600k but will be getting i5 4670k.
Psu: 750w
These cards are very close. The gtx 770 is thought to be an insignificant 2% better than 280x. I would say for go for the cheaper one. Either card will put at the ultra preset @ 1080p on both arma and battlefield.
yeah only trade off going w/ AMD will be a little more heat.... Your current CPU is probably a fairly large bottleneck for ARMA3 w/o an NVIDIA card capable of on-board physx processing
