Hey i built a gaming pc roughly 2 months ago with a i5 3470 and a radeon hd 7870 sapphire. It can sustain an average of 60 fps on bf3 ultra but somtimes i get drops to around 50 fps. So if i would add in another 7870 will i get the maximun out of it =S? im scared that the cpu i5 might bottleneck it somehow? is it powerful enough =o?
Thanks in advance
