64bit from what i've read would be a good investment for the future of your
machine if you plan on keeping it for more than a couple of years. even if
you got xp64bit you prolly wouldn't see that much of a difference in your
day to day (windows) use (3200+, winxp/xp64)
i just bough a machine with the 3200+ and it really cranks it out in the
gaming arenas and i look forwar to the day that software catches up to the
technology(for a change), but on an older machine you may be waiting longer
than you computer lives
