It's true that HD can be choppy in both VLC and Quicktime player. But
IMO your explanation is wide of the mark.

I managed to fix the problem in VLC by tweaking some preferences, and in
Quicktime player by installing Perian, suggesting to me that it's not
the hardware capabilities of the card or the Mac's access to the
capabilities that cause the problems with HD playback.
