I just upgraded to a 7790 from a 5850, I thought I would see a huge performance increase, however it seems neglegible. Running battlefield 3 at low setting in any graphics mode on a 64 player server is choppy. I'm using a T5 XE motherboard with 8 GB DDR3 and an Intel I5 760@2.8 GHz, my question is what is the biggest bottleneck that I need to fix?
