There are no waterblocks for this card yet so I just have it on the stock air cooler for now, haven't had a chance to do anything more than install it and the latest driver, haven't even run a single benchmark or game yet but it's waiting for me when I get home... OC potential looks good so far from what I've seen from other enthusiasts @ overclock.net with many achieving core clocks beyond 2GHz, almost all above 1900MHz (and usually sustained at that). Just need better cooling and the ability to raise the power limit and these cards will be absolutely bananas.
