Hell, an Athlon XP at 800MHz would make quite a nice desktop box -
the only things that need more than that kind of oomph are games,
and even then only the new ones. For normal use, anything made in
the last two years is plenty good enough . . .


PS: If you /really/ want an old slow box, though, I'll happily swap
my Athlon 550 for one of those shiny 1.6GHz XPs . . . . . ;-)
