Multiple Video Card Question.......

I have a Small Form Factor Computer, with 1 PCI Express Slot and one Standard PCI Slot. I want to run 3 monitors (2 currently running at 1680x1050 and another hopefully which would be at 1920x1080). I currently have a 512 mb Geforce 8400 GS (low profile) running the two monitors. If I want to add a third monitor (or actually TV) how can I do this?? (P.S. this is not for any type of gaming, it is a business/workstation where the TV will be used as a monitor for presentations, sales meetings, etc.) Will it work to add just a standard PCI graphics card and run the two cards independently of each other, or do I have to buy some super expensive 4 port low profile graphics card?

Can I add this one and run 2 cards independently: http://www.tigerdirect.com/applica [...] CatId=1603

Or do I need something like this: http://www.biz.newegg.com/Product/ [...] 6814195086



IF ANYONE ELSE HAS A DIFFERENT IDEA TOO, I WOULD APPRECIATE ANY HELP!
