It's a single card is NOT a valid argument, they are different classes.
Nvidia releases a card, then later on releases a Dual GPU version. They did this with the 7900 series, 8800series (9800 is an 8800), and now with the G200 series.
It's 2 totally separate cards on 1 board, there is separate memory, and the data goes through an SLI connector just like 2 cards.
The difference between SLI and single card is very big. The 9800GX2 doesn't really give a smooth gameplay experience, there is micro stuttering and the lowest FPS can drop quite low.
Anyway, all I'm trying to say is just because you bolt on 2 cards onto 1 board doesn't make it comparable to 1 card.
You say that both are the most powerful cards of their generation, but the most powerful card of the G200 generation will be, you guessed it, the GTX280 X2.
