        That's interesting.  I have a 6600 and it (mostly the X
server) is just maxing out an Athlon64 3500+ when playing a 720p video
in a 1920x1080 display.  It plays fine but there's no headroom
(eg. for >1.0x timestretch).  Playing a 1080i video uses less CPU.  I
had been assuming this was due to inadequate Xv support since an older
card (PCX5300) was using much less CPU for 720p.  (Unfortunately, the
video quality of the older card was really bad at 1920x1080 so I had
to return it.)
