A 1.9Ghz A64 will be sufficient to play back ATSC broadcasts, while at
the same time running one or two commflags at better than real time. On
the other side, the 2.6GHz chip is still to slow to play higher bitrates
coming out of an HDPVR.
Back to VDPAU, it really makes processing capability irrelevant. All
video decoding is done on the card, leaving the processor to do whatever
commflagging/transcoding/other jobs you want. Better to get the dual
core chip here too. Also, unless you intend to play games on this card,
don't bother with an 8500. Grab one of the newer revision 8400s
(~550MHz as opposed to the older 450MHz usually indicates G98) or a
9300/9400 chip. Nice to have around on the off chance you come across
some VC1 you want to play.
