Hi all! I am having some problems with my gtx 780 that I have paired with my 4670k at 4.2 . When I was playing bf4 I noticed at some points my frame rate was going down so I pulled up msi afterburner and was seeing my gpu usage going from 99% all the way down to 53% for no reason and its always jumping around. The same thing for Batman Arkham Origins when gliding around gpu usage and fps are down. If anybody has had this problem and know what is wrong please help!
