It may still be worthwhile, if you live in an area with expensive electricity. I've forgotten the exact numbers, but the XP-M CPUs tend to use significantly less power than the regular desktop CPUs (something like 30-40+W less). A few months back, I built a 2200+ XP-M-based system which only uses up around 80-90W, and this could have been even lower, had I not also installed a power-hungry TV capture card (Hauppauge PVR-250). -- Darryl Okahata darrylo@soco.agilent.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Agilent Technologies, or of the little green men that have been following him all day.
