I have an older HP desktop. I would like to figure out how to upgrade to a video card for two monitors?

Is there a scanner utility that I can go to that will determine my current hardware and recommend the right card?|||It's up to the video card. You need a card that can support two monitors and you need to determine if your motherboard can support the card. How old is the desktop? Does it have a PCI-E x 16 slot for video cards, because most if not all new videocards are in that format.
