Hi, currently I have two computers both with with dual monitors. Both computers are using the ATI 9600 pro dual monitor support video card. On one of the computers I wanted to add a 3rd monitor. The question at hand is do I need to buy a completely new video card that supports 3 monitors and take out the current card, or can I add another video card to the pci slot (the current video card is in the AGI slot) and then put on a new monitor? Will the computer recognize 2 video cards at once and allow my real tick to be spread across all 3 monitors as realtick is currently now spread across 2. Looking to go shopping this weekend for the card and monitor appreciate all help. Thanks.
