When i play warcraft 3 and Counterstrike Source i get artifacts then source freezes, but wc3 doesn't. When i play Unreal tournament 2004 i don't get any artifacts. What could it be. Its all stock cooling. Think my video card is dmg or getting too hot. While i was playing wc3 the highest i've seen was 81C but everyone says that normal. Think i should decloking it? Or what? Thnx for the help.
