I've been holding out so long to get one and it DOES perform well, just really a case of putting up with the noise. Thing is, I'm running a gtx280 and on one of the reviews it said my card was louder at load, if that's the case then I'm not too bothered as it's not a problem when gaming with the speakers turned up.
The price is what i expected, but isn't ideal knowing that a similar performing card(5870) is much, much cheaper. However, I have the 120hz monitor and the 3D vision goggles, something ATI cannot provide at this moment, so it makes sense to stick with nvidia for these reasons. I just hope I don't get bumbed in the gob by a massive price cut after a couple of weeks.
