Hi, I recently bought a second hd 7850 for my pc. My CPU is an fx 6300 at stock clocks. However, in games like battlefield 3 my fps is only like 40 on ultra. I was wondering if this is a CPU bottleneck? If so I was wondering if I could get some good overclocking suggestions. By the way, Battlefield 4 runs perfectly. I think this is because it supports the multi threaded performance more than bf3. Thanks!
