I bought my new amd fx 8350 a few days ago on amazon (My last processor was a amd fx 6100). After i installed it i start playing games like (Assassins creed black flag, Battlefield 3, splinter cell Blacklist, and Guild Wars 2 my main game) 2-5min into various games i have constant heavy fps drops from like 150 fps to 28 fps in game. I dont had this problem with my old CPU. I dont know what to do, i'm very bad a PC stuff. The Graphic settings dont matter i have the fps drops on low and high settings.
When I play, the temperature is around 45-60C
