looking around for this as i was thinking of building a pc in the near future and for my brother soon. noticed that alot of the cheap deals (Student price deal) were upgrade only version and you had to have windows installed. i also noticed that the full version were more expensive so i thought this was a good deal for the full version or the upgrade version is a few pence more if you like. also the same price @ amazon and these seem pretty cheap after all the good deals went. hope it helps somebody :)!
