8800gts g92 artifact?

[claytonian]

Hi I just bought a new 8800gts g92 and after about 2 weeks, im getting wierd texture problems in my games, 2 worlds, gh3, WoW, and Gears of War. All of my games after about 20 mintues i get random textures where they shouldnt be and text gets pixelated and blurry. I installed newest drivers, and patches for the games, and ive downloaded riva and turned up the fan to 90 percent, so i know its not a heat problem. What do you guys think i should do, I just cant figure it out!

What temps does rivatuner report? It does sound like a heat issue, or maybe the card is a lemon with bad gddr or something. Also, what kind of PSU do you have?
