I'm not sure what is causing these anomalies when I'm playing 3D rendered games. Holes in the surface of walls and ground. Flashes of what looks like miss-placed textures randomly appear. It seems to start after a few hours of playing. Possibly an over heating issue? I probably answered my own question though. What should I look for and how can I diagnose it?
install evga ocsanner x check on the enable scanner box,run the different types of GPU stress tests it offers about 30 mins each.[Monitor closely,stop the test whenever artifacts are detected]
If artifacts are reported its bad news,you'll have to return to the stock clocks of your gpu.If you're already in stock clock speeds you should have to RMA your card.
Ok I installed a temp reader for my system called PC-Wizard. My GPU peaks at about 50 degrees when im playing games so its not over heating. Its and Gigabyte Radeon HD7970 and its got a decent cooling system.
