Anyone else running CF 7870's and played BF4 on ultra settings? I average about 70-85 fps depends on the map but hit 40 fps minimum or lower when in a fire fight or explosions. This causes me to lose most of my one on one battle because of my FPS dropping below 60. Seems to be the game or CPU issue. Am using a FX 6300 OC to 4.5GHZ. I would love to know how other CPU's performs so i can know what to buy for my next CPU upgrade! thanks in advance.
