Ok... So I've had the card back for about a week now. Played a grand total of around 10mins of Battlefield due to being busy with work and other boring stuff. Sit down for a Saturday afternoon gaming session and.... *drum roll*

Nice.... Card was 60deg at this point. The box has a load of BS on about the card meant to work for 12 years or some **** at 70 deg.
Are you still getting the artifacts elsewhere, aside from bc2? BC2 seems to have some sort of rare artifact issue on some maps with the 400 and 500 series. I, and some friends i game with who also have nvidia 500 cards sometimes see that exact corruption, mainly on that map oddly enough.
