Hi again
install and Run the Windows Vista Upgrade Advisor t will tell you if its compatible

Also if you feel you dont like vista fo what ever reason after you buy your new pc you can format HDD and buy a retail package of windows XP but its beng cancelled on June 30th so buy it ASAP if you decide to.
