Nvidia isn't any better unless you're using XvMC. I've got a GeForce
6200 in my windows box (Athlon 1800) and it dies playing a 1080i content
clip I have for testing. Play it with the Nvidia Decoder trial from
their website, and it is rock solid playback. I'm guessing that no
matter what, unless your video card drivers are *really* supplying the
accelerated playback, you're always going to suffer until you get
excessive CPUs.
