If my memory serves correctly, my A64 3500 w/a PCI-Express 6600GT gets pegged
more (percentage-wise) on HDTV playback than does my Athlon XP 3200 w/an AGP
6200, with very similar configurations between the two. I'll have to
double-check what sort of cpu usage the 3200 is getting on both 1080i and
720p content now that I've bumped it to FC4, push a 1080p display and use no
deint filter...
