This is currently one of the best cards on the market, comparable to the "Geforce 8800 Ultra", a $600-750 card by Nvidia, for an affordable $349.
The card supports Pci express x16 2.0, which none of the current Nivian cards support, has a default clock speed of 825mhz, has a full gig of onboard memory, and is rather large.
Person 2 "yeah? Well my 8800 gtx cost more, so it must look better, right?"
Person 1 "Why, again, are we friends?"
