Is a single GTX480 able to game on three monitors ?

If not, this can be the source of the TDP discrepancy. Maybe Eyefinity'ing at 3 monitors draws significantly more power than a single monitor setup. And since TDP is supposed to be the maximum, AMD was forced to measure it at 3 monitors whereas Nvidia measured it a 1 monitor because a single 480 isn't able to game on three monitors.?
