Ok, a friend of mine has a Creative FX5600 128MB AGP8x card, and is having a few problems.
Completely randomly the card will spray up artifacts all over the screen and corrupt in games...but only games based on the Q3 engine
Example of corruption:
The temperature of the card is around 50 degrees in games using his fan controller, and I think the case is around 35 degrees.
I have a feeling it's b0rked graphics memory as opposed to overheating, but what does everyone else think?
Would underclocking help at all (this card has NEVER overclocked more than 1MHz without having problems)
