Hi! Today I was playing Fifa 06 World Cup, and Re-Volt (very old game), and then my Powercolor X800GTO started to do some weird things. The games had missing textures, the sky had big gray blocks on it. I then touched the card, and it was damn hot. So I think it is overheating. I have good case airflow (1 front intake, 1 back exhaust). The card is using the stock cooler (I'll post some pics later). It didn't lock up, because I turned off the PC when I started to see that. I'm looking for this cooler for it: http://www.newegg.com/Product/Product.asp?Item=N82E16835186129 Is this a good cooler? I will not use the card until I get the new cooler. I seem to be fine with the 6100 IGP card :haha: I'll post some pictures of my card, and the stock HSF, if that helps. I just have to wait until my camera's batteries recharge to post the pics. Thanks!
