Check it out for yourself there's always post-decoding processes for the
cpu.
AMD HD2600Xt and 8600 GTS are less cpu intensive than a 8800 GTX or
HD2900XT and the slower the cpu the more cpu utilization.

Of course there's post-decoding processing, but the same
could be said about any files that play fine. That alone is
no evidence.
The evidence will be observing it actually trying to play
such files. There's really no point in trying to estimate
what can be readily tested. By tested I mean playing
several 1080P clips since some will require more processing
than others.
