Could an i5 @4 Ghz bottleneck 2x6950 2gb? Or what could be the cause of Battlefield BC2 negative scaling? The temps of the gpu's are around 65 C, so i see no temperature bottleneck. Should i overclock the CPU more? Show your creativity here my friends, I'm really stuck p.s. I game at 1680x1050, and scaling in other games like Metro 2033, AVP, Crysis 2 is great.
