Right i’m buying a pc on ebay and it needs a new HDD and OS i’m looking at Windows Vista Ultimate 32bit. My question is what is the difference between the 32bit and 64bit versions?
Truly, there is no difference. All you need to do is check if whether you have a x64 (64-bit) or a x86 (32-bit) system. If you have the 32-bit system, then buy the 32-bit version and vice-versa.
From windows itself:
