Not surprising, that seems to be the accepted wisdom that that CPU  
won't do HD. There's a reason you can buy that CPU new for $30 these  
days (it was $40 last week).

It should almost certainly work. Jarod Wilson has said he's getting  
good results with a CPU in that class. I'm getting good HD playback  
with a Opteron 165 clocked at 1.8 Ghz., although that's a dual-core  
chip so it's not really a fair comparison.

(If I'm putting words in your mouth Jarod smack me, but you've said  
that many times IIRC.

I'm assuming that's the socket 754 "clawhammer" core Athlon you're  
talking about.

Even if the Athlon 3000 will work, which it should, you are still  
putting money into a system that's basically obsolete, or at least  
will be so far sooner than a socket 939 box.

It's really a question of spend it now or spend it later, and what  
your budget will allow. I can't recall ever hearing anyone complain  
about having too much CPU horsepower.
