I want to buy Vista, and I notice that sometimes it is mentioned that one is 32 or 64 bit. Are they really separate? If I buy a 32 bit, meaning to get a 64, am I SOL?
from the reading i have done, if you buy the 64bit version you may have trouble finding drivers for your hardware. but with 32bit, if you have 4 gb of ram you will only use approx 3.3gb
