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!
 
Solution
40 fps is about what I would expect from stock settings on a 6300/7850 setup, according to benchmarks the 6300 gets about 41 to 54 fps in battlefield 3. where your video card CF should play at a 87 to 98 fps depending on your resolution. both estimates are on UQ@1080p with both cpu/gpu at stock speed. but if you drop it down to HQ@1080p you should hit that 60 fps sweet spot. if you have your heart set on the UQ i would look at over clocking, i have a friend with the same setup as yours but over clocked, and he is getting 60 to 68 fps on battlefield 3 UQ@1080p.
