That CPU should work without XvMC. For reference I have an Athlon 64 3200+
and I get ~40% idle while watching 720p and 1080i with Bob. I scale all
output to 720p and I'm currently running SVN from about 2 weeks ago.
Of course it took a lot of tweaking to my setup and specifically my modeline
to get where I am. That, plus the new nvidia driver with UseEvents enabled.
I too was thinking about upgrading to dual core, but with the new driver and
modeline I'm using, my system has been rock solid for a couple weeks now.
HD has never looked so good.
