SemiAccurate is reporting the Nvidia 480GTX uses 275 Watts of power. There, that is all you need to know, other than how much you electric bill will jump when you start using these things. Remember, this is about three 100 Watt light bulbs in your system, or eleven CFL equivalent bulbs. Think about running these things in SLI. Think about running these things in a four-way computer server. I cannot see how this can ever make it into a laptop, even if you cut it down. Maybe the second revision will be better.
