Choppy gameplay in all games

[stealthimpulse66]

My games over the past year or so have been running choppy and having FPS drops. It used to run games great with no hiccups. Games are getting extremely low FPS drops and I need help finding a solution. Even after formatting my hard drive I saw a definite speed up in performance that then slowed down over time.I am running on all of the latest drivers and i have also cleaned my computer. While playing my CPU usage is roughly 50-75 percent, and using only 5 gigs of Memory.The CPU was running 60-70 degrees, which is a little high.

Spec wise shouldnt lag too much.

May be software/ windows issue.
Better do a clean windows instal from time to time
