I'd love to have Python and Numpy optimized for the Athlon.  I will have
to wait for gcc3.0 to get absorbed into FreeBSD.  (Mandrake linux has a
beta that uses it)  It turns out that mpg encoding runs at 10x the rate
on my Athlon DDR machine compared to my laptop due to the highly Athlon
optimized "GoGo" encoding program.  Rob.
