How long will 2gb be enough? because games like BF4 reccomend 3gb of vram. I know the 280x is more powerful then the 760 but its really stretching my budget if I get the 280x, same thing with the 770. Also would 2gb be enough for 1440p? or would 3gb be better?
2GB is enough for 1080p. Why not consider a 770?
because the 280x is better 384 bit bus width and 3GB buffer
That doesn't automatically mean it's better. The 770 usually out performs the 280x
