Artifacts on textures when forcing AA through Catalyst

Hello all. I have a Gigabyte 7870 OC that works great and runs all of my games maxed out. I monitor the temperatures and everything runs nice and cool. However, when I attempt to force override AA through Catalyst all of my games (Skyrim, Borderlands 2, Dishonored, Heaven benchmark) get flickering gray boxes all over the textures. When I put "use game settings" everything works as it should, as does in-engine AA. I have tried different catalyst verisons (12.4, 12.5, 12.7, 12.8, 12.9) as well as different settings of AA (turning morphological filter on and off, adaptive, SSAA, etc..). I have emailed Gigabyte and they cannot help me other then RMA'ing the card, which I don't want to do unless I REALLY have to, since I believe this is somehow software related. I am running Windows 7 64 bit, on an AsRock z77 Extreme 4 motherboard. Any help would be appreciated.
