Hello, I have the 7870 OC, and this has been happening on every version of catalyst I have tried (12.4, 12.5, 12.8, and 12.9, etc). When I force AA through either the CCC or in game, gray flickering "box" artifacts appear all over the textures in all of my games (Skyrim, Shogun 2, Borderlands 2). The card runs flawlessly despite this. I am running on Windows 7 64 bit and have a Z77 Extreme 4 motherboard. My monitor is an Asus and is connected via HDMI to the card. Not having AA is not that big of a deal, but I want to get the most of what I paid for.
