The Inquirer reports the NVIDIA G80 GPU is late because of another respin, it's now expected that the card will arrive somewhere at the end of November.
This means launches in the middle of the Christmas shopping season, and short supplies after that, make sure the kids know what they won't be getting.
So, it is going to be late, that is not the ugly bit, board partners are telling us that it very well might have an external PSU to power the beast. We told you it was going to be hot, but not as hot as an R600. Either way, this does not bode well for either card. Think of a monster with a brick to keep it from running away.
