I've had this problem for a while now and decided to look for help here. I have an AMD FX 8350 and a GTX 660 video card. When I play games, the CPU usage drops for a few seconds and, while that happens, the fps dramatically drops. I've tried disabling Cool 'n' Quiet, Turbo Core and C6 in the BIOS, but there was no change. I've ran out of ideas and I'm hoping I can find my answer here.
