I got my GTX570HD. At 30% fan speed its very quiet. But if I leave it at that while gaming my card gets to about 90 degrees. And while playing it seems like my card starts to get a little choppy while playing BC2. At what temp would the card start t throttle or slow down my game play? Because when I set it to auto the fan speed gets to about 60% and its way way to loud for my tastes. Also when gaming with a ATI card like the 6870 or 6950, it seem like it plays it smoother than the GTX570 I know that sounds crazy but it really seems like that. Is BC2 more optimized for ATI than Nvidia?
