if you want to pay the least amount of money and don't plan to do any gaming, then in addition to your current card, buy the cheapest videocard you can find. You can use almost any combination of videocards.
for example, you can use a GTX 460 in conjunction with a geforce 2 to drive 3 monitors.
if you have onboard video that auto disables it's self when an additional card is added, then get the cheapest eyefinity card you can find that has 3 display outputs.
depending on your needs, you may be able to move to 3 displays for as little as $20
