You can replace the fan on the graphics card? I only got artifacting when i overclocked. I don't as of now, with the graphics card being on normal settings. The highest temp i recorded was only 60 degrees on the 81.89 drivers while overclocking. It can't be the actual overheating of the card. Should i perhaps try overclocking on a different driver, or is the driver i have now already good for it? It is not overheating, and so just because of the graphical abnormalities it sucks to not be able to keep the high settings. Could something else possibly be interfering with the graphics card on the higher settings?
