Dont believe everything ya hear. If he got Ultra on that vid card it was either at a lower resolution or with settings turned down. The 7870 is a decent vid card, not a BF 4 ultra kinda card.
kk but should my GTX 760 run BF4 1920x1080p at 55-60 fps ultra? I also heard that windows 8 increases your performance in that game, so is windows 8 worth it? Thanks!
