From BSN regarding GTX480:
At the end of the day, the shroud of secrecy that Nvidia raised around their walls only lead to the lack of trust on the side of their partners
Unfortunately, this has only reinforced what I have been saying: If Nvidia had the goods on ATI, we would have heard about it. I have held off purchasing an HD5870 to see what the GTX480 has to offer, but it looks like it will be just par with ATI's offering, minus the energy and heat savings. Time will tell.
