Just do what i did, d/l or borrow the 64 bit version then use it for 30 days until the tryout period expires b4 u buy. It helped me iron out any bugs & i didnt have to worry about not being able to send the oem version back to the retailer (which you cant do). Also, i decided to buy the retail version from ebay, since i only wanted the 64 version of ultimate, i got it for around £90, considering the oem version is around £110 & the standard retail is £300 i saved a small fortune.

Also, save sp1 to your usb pen so the first time you log on to your newly created vista user account you can install it.
