I have a HaF 932 advanced case, EVGA gtx 670ftw graphics card, 16GB of Gskill Sniper memory, MSI x58 pro-e motherboard, and Intel 960 cpu. I play WoW and some fps games and I have low fps especially playing WoW. I was wondering if I should replace the motherboard and cpu to improve my system performance or if the current gear just needs to be tweaked? If replacing could you offer some suggestions on parts. Disregard the parts in the signature that is a different rig. Thanks!!
