I just upgraded my PC's CPU and GPU from a phenom x2 ii 810 and a 9600GT to an i5 2500 sandy bridge and a 470GTX MSI Nvidia.
I've noticed major fps improvement in most games such as The Witcher 2 and World of Warcraft but I have been facing a major problem with my only two steam bought games, Call of Duty Black Ops and Call of Duty 4.
I would get around 90 FPS and it will drop constantly (every 1-3seconds) to around 15-25 fps and go back up. This made both games unplayable.
any help would be highly appreciated. thanks in advance
