So, according to this link, they've met the standard of the single GPU getting as good or slightly better performance than last gen's dual card. If it had been delivered at the same time as the 5870 last fall, everyone would be perfectly happy. With a 6 month delay, I expect people are going to be underwhelmed (at least the objective ones, the die-hard green fans are going to claim the performance crown makes the delay irrelevant). Pile on top that the card is (probably) going to be extremely hot, power hungry, expensive, and produced in limited supply. People are going to be disappointed.
