With a $680 price tag and only "up to" a 90% performance increase from a 8600GT, this card won't be very popular. From what it looks, does anybody actually believe the upcoming 9 series deserves to be labeled as a new series? They should have just labeled the 9800s to 8900s like what they did with the 7 series.
The thing that gets me is that usually the marketing on this stuff is over exaggerated, 190% 8600GT power sounds pretty weak for a high-end 9 series card. Maybe it's a typo?
