tommorrow i'll get my new computer. it's 32 bit vista. but i would like to have it 64 bit. but what are the advantages? and do i need to reinstal vista all over again when i update it. and how do i update it?..... lots of questions but i would like to have them answered ....

try this

1. you cant update 32bit to 64bit, its an own Operating System
2. advantage: you can use more than 3,25gb RAM, 64bit ingame graphic... (dont see much differences to 32bit...and not every game supports it)
3. disadvantage: driversearch will take longer :O

not with vista -.- just push windows update and done...
