FPS different every day?

I recently upgraded to a gtx 980ti and was playing ARMA 3 on Ultra with 60fps-75fps on average and GTAV on High with roughly 120 fps. Now I notice that even though my settings are exactly the same my fps in ARMA has dropped to 30-45fps and GTAV dropped to 20-45fps on average.
Graphics card is roughly 4 weeks old.

Any idea as to the cause?
