This is going to be a 1 very stupid question in my opinion. Im wondering.... I have OS Windows XP Home Edition which is only 32 bit (I think) and im going to buy a new graphic card which is a 64 bit graphic (Sapphire Radeon HD 5450 "Silent" 1GB) and im asking myself if the graphic card has anything to do with a 32 bit windows. Will it work? is there a problem with that?
