Barcelona was just announced yesterday. I wouldn't want to be betting
my business on it just yet. Plus, AMD usually is able to up the clock on
their chips pretty well after they've got a few production runs under
their belts. If you've absolutely got to have something today, I'd say
Intel would be a safer bet. If you can afford to wait 3-4 months, then
you'll benefit from some industry experience as well as production
maturity with Barcelona, and can judge then which better fits your needs.
