4W4K3, I OC'd mine to 570/999 but I started noticing textures blinking a little within far cry. Haven't tried other games, but as of right now I don't think the core wants to really go above 550 or so, and the memory probably around 960, around there I think on higher 1280x1024 settings with 2x AA, and AF that it was still blinking. I gotta wait until I can get a good water cooling setup, get the MAZE4 GPU block, and some tweakmonster RAMsinks and no doubt it'll probably OC better.
