So I been looking for a while for few answers but cant get a very straight answer. Help if you can with all. This applys to all GPU but using mine for example. I have msi gtx 680 OC at 1202 core stock volatge, temp don't pass 70 degrees on 1080p monitor. Questions: Does OC your memory give your noticeable performance boost, I say noticeable because of course it will but is it negligible? My stock core clock is 1050 does my now OC 1202 with stock voltage put extra stress on the card or damage it severely? Does my OC give that much or a noticeable boost in fps and performance? or should I lower to 1150 or back to stock?
