Recording an HD stream takes little or no CPU, just disk I/O. If you use VDPAU
you won't need much CPU even to play back h264, it's all happening in the GPU.
It's playing back (decoding) HD with software that the WiKi was referring to,
if you want to have the capability to do software playback that's what you
would need, and you would still be lacking some of the nice de-interlacers
that VDPAU makes possible.
With VDPAU 3 Ghz. is not needed, at least IMHO, unless you want to have the
ability to do software decoding, or do really fast transcodes.
