Given that he will be getting a 9400GT he'll presumably be using
VDPAU. I can't speak for the AMD, but I can testify that a four
years-old Pentium 4 3.0GHz with VDPAU is sufficient for a combined
frontend/backend. (As Jean-Yves says, the box can play HD MPEG-2
without VDPAU, but what's the point nowadays?) If you do go ahead and
break up the frontend and backend (as you should if you have a
choice), use the Pentium as the frontend.
