Is this machine an exact copy of the machine you are comparing it to?
I find folk want the excellent numbers you see in a review but them they don't duplicate the machine the review used. Also you find folk install registry cleaners, an old copy of XP, Spybot (dated things) or again, forget to copy the machine they really wanted.
I just finished building my new gaming rig, which consists of:
Intel i5 3570k quad core processor @ 3.40GHz
Nvidia GeForce GTX 680
Windows 7 Home Premium 64-bit edition
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, Team Fortress 2, 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.
