To access and use more that 3Gb of RAM you need a 64 bit OS. XP and Vista BOTH come in 32 and 64 bit variations.
So make sure read the fine print. XP-64 is rare, where as Vista64 is common and getting more so. You can buy Vista32 and DL the 64 bit version from MS for free. It's the same price for 32 or 64.
Along those lines...anyone thinking about switching to XP64 be sure you can find drivers for your hardware...it's notoriously under supported. It just never really caught on I guess... I have no idea how Vista 64 is, but that's always been the problem with switching to the 64 bit version of XP...
