I don't mean to say that only an LN2 bencher can buy the thing...but really those are the users that would welcome something like this because they won't have to worry about ever running out of juice.

@Napalm,

Yes but it would be hard pressed to overload 1 rail... there are 4 dedicated PCI-e lines each on a separate rail....so 2 8800GTX's would have 4 12V rails to draw from. That means each connector on the card would have its own 12V rail.
