Info on how to OC it if anyone's interested:

I've been reading a lot since this morning and people are claiming that they can easily get the Ultra's speeds (425/1100) on stock cooling, so hey, why not?
Plus the card is built in such a way that if the core gets too hot, the voltage drops to prevent damage to the card itself, so apparently it's difficult to actually destroy the thing.
Has anyone tried this yet?
