Yeah, while your logic is true, two cards should beat one card alone. But when you add price to the eq, it's another ballpark. Two lesser cards (in price and performance) can beat or be very close to an extremly expensive card.
my logic is go for the extremes...i will never buy this card, but i enjoy the fact that is is amazing. i like to see nvidia on top of the hill. IMO i dont care how much it costs because im not going to buy it...lol
