64-bit,or 32-bit{vista}?
Answers:
Take it from someone who purchased Windows XP 64 bit a couple years ago, stay away from the 64 bit operating systems right now.
The biggest issue is that very few companies have developed drivers that work on the 64 bit system. Everything still operates in the 32-bit world.
Right now, do not get 64-bit for Vista. Too buggy and not enough support. Also, you might not be able to get 64-bit to work for your computer anyway, because this requires a 64-bit processor. Stick to 32-bit for now.
