I wouldn't buy any nvidea card at the moment when the Radeon X800XT or X800 Pro beats them all and dosn't require special power source. Far better card imho, had the pleasure of installing one and running some benchmarks in a friends computer last weekend we were getting 55fps in Far Cry benchmark. Over 350fps in Quake 3d LOL.
Hope to buy one for myself soon. Overkill for AH2 though.
