im buying an alienware pc with vista pre installed on it, is vista good? does it interfere with any programs? im buying the pc to play WoW on and ive heard vista interferes with alot of programs and doesnt let them run or something, just wanted some info. i already know its bad thanks in advance.thanks, i just went in there and changed the option, for $100 more they will install windows XP professional instead (kinda weird theyre charging more for an older software huh?) and my major problem is RAM and im getting 4GB i dont want anything to eat up almost half of it lol
