I would go with vista if i were you. if you are getting a DX10 card you may as well, that and someone commented on if XFX are still crap? I got an xfx 8800GTX and haven't had any problems with it @ all, but before i built this computer i never really took any notice of other companies and their past, lol. it was either this one or the asus one, and this one was $10 cheaper and looked cooler, haha
