It's a single card with two GPU's. It take up ONE PIC-E slot meaning it is ONE card. You can make something with 8 GPU's, if it takes up ONE PCI-E slot it is ONE card.
Sure I can see how someone says it's two cards, so what you have then is the best bang/buck SLI option as this thing stood toe to toe with a $1,000 worth of cards in SLI mode. Don't have SLI however, well you can pretty much experiance it now without replacing you motherboard.
Either way you look at it this is an extremly powerful card, they just put it out at the worst possible time.
