god****it. i just wrote like a ****in essay on this same exact topic before gizzy reset the board.
basicaly, you need to find a video card that uses different resources than the intergrated one. which shouldnt be that hard to find since your current card in built in to the mobo and most likely has its own resources.
also, since you have an intergrated card, you also can buy a dual head card, with output to two monitors from the same card. then you will be able to output three different to three different monitors.
