<a href="http://blogs.zdnet.com/Ou/?p=440">Choosing between 32 bit and 64 bit Vista.</a> -------------------------- If you have a 64-bit compatible processor I recommend you always go with a 64-bit Operating system. 64-bit operating systems are backward compatible with 32-bit applications, so you get the best of both worlds. The only problem is finding compatible drivers for older devices. -------------------------- Also, 32 bit Operating Systems are not able to map more than 3.2 GB (approximately) of RAM, so if your machine has 4 GB or more, take this into consideration (if you have a processor that supports x64).

At its most basic level the big difference between 32-bit and 64-bit is how memory is accessed in the PC. 64-bit is faster and more efficient if you have a processor that supports it.
