I'm looking to upgrade my old P4 2.4 A lot of the new processors say they support 64 bit, but can the chip still be run in 32 bit mode? I'm just looking to upgrade mobo, processor, & RAM and don't want to upgrade OS to Win XP 64 just yet, I'd rather stick with XP Home.It would be nice to have a 64 bit capable chip for the future. Is this possible?ThanksJim

Hi JimNo problems. I'm running Win XP on an AMD Athlon 64 bit cpu :-)Ulf

Many thanks Ulf.Jim

Same here. Go with a Socket 939 mother board and a AMD 64bit 90nm processor. It's no guarantee, but it's the best future proofing you can do right now. Works great with everything I've tried.Tony=http://www.flightsim-bevs.com]
