I just finished building my new gaming rig, which consists of: 16gb RAM, Intel i5 3570k quad core processor @ 3.40GHz Nvidia GeForce GTX 680 ... However, with this new rig (which I thought would probably be able to pretty much destroy any game on ultra), I am having strange performance issues (aka lower than expected framerate), in World of Warcraft, DOTA2, The Witcher 2, Diablo 3, amongst other games. I have reinstalled drivers, and made sure GPU fan is high enough so it isn't overheating. Anyone please have any ideas why I could be having performance problems like this? Thanks in advance.
