I'm definitely going to be wating awhile before going the 64 bit route. I've got an AMD 2200+ XP right now. I'm hoping that as soon as they really start to push the 64bit processors hard, I'll be able to upgrade to a P4 3.2ghz 800 FSB with some ram for roughly $250. That'd be more power than I'm used to and would keep me going well into the time when 64bit becomes tried, tested, and standardized.
