Sadly enough a stacked PCI-E Connector aswell which means no Arctic Accelero XTREME III compatibility......why It would fitt the Twin Turbo II tho.
Why would you swap the fan? The whole purpose of this card ( and a large part of the price ) is the third party cooler. You'd have to be pretty thick to pay the extra cost for this card and take the cooler off, considering that's why it costs more.
Heavy AA can also eat a few hundred megs on top of it, especially for nVidia cards which have so many options because of nVidia Inspector. 4GB is no longer a waste. I'd buy a 4GB GTX 680 if they didn't cost their own weight in gold.
Ludicrous pricing in UK. Hell even the vanilla 680 is ridiculously priced. Once the 7950 hits £250 I will bite there, but 500-550 for this. NV can ram it.
