Just wondering for the furture, whether my truepwoer 330w would survive the upgrade to 64 bit. I have looked on Antecs website and they say that it can do 22A on the 12+ rails (is that good?). I would only have two optical drives and 2 hardrives at the most. I would keep my 6600gt and run 1gb on an 3000+ winchester or 3200+ winchester. Do you think the PSU would be ok?John
