Forget about XvMC. It's a relic of a past era where our poor struggling
sub-2G single core cpus _needed_ some graphics processing to be offloaded in
order to survive. So, the poor little graphics card endured constantly
cooking up a storm doing XvMC, and without even a fan to cool its brow.
Now, I believe you're better off letting a nice little dual core do the
hard work. It's better equipped to deal with the heat output too.
Worst of all, XvMC comes with some tedious artifacts. You don't get anything
for free. My suggestion is have the graphics card do no more than it has to,
and provide the necessary grunt via cpu instead. I have a 6200 and a 7300
(two systems), and I really can't pick between them. They're both excellent as
long as I don't try to include XvMC in the mix.
(I could really use a "Loooong break", can you recommend a good source?)
