I was OCing my gtx 770 and it has now started stuttering in games I dont even get solid 60 in star wars battlefront 2 which is 9 years old! There is no bottlenecks used to work fine with my old 760 and for a few days with the 770 I set the core voltage to +12 has this damaged the card because I pulled it to the max though I used msi kombust and that produced normal results which was wierd
