Ive tried vista before a few times, and while I liked it, I always had problems playing games (Going from odd graphical glitches to wierd freezing (both mainly in cod4), to complete lockups).. I have no idea why this happened and have been forced to use XP because of it 
If I try windows 7 am I likely to find the same problems given that its based on similar architecture?
