How to insall dual monitors on 2 graphics cards ?!

[R9]

Hi
I want to install 2 monitors on my PC ( Intel 945GNT motherboard), and already have two cards, a built-in GMA950, and a GeForce 6200 (PCIE), I read many articles on the net saying it's straight forward; just install the two cards and there drivers, plug the two monitors and configure the display settings to use them.
but my problem is that Windows XP recognizes only one cards (as if there is only 1 card on the system), so it only doesn't recognize the other monitor.

To my knowledge, you can only run either the on-board graphics, or "external" graphics card, PCI, AGP, or PCI-e.

I got my 9600 pro for $80 and it has a VGA and DVI port, along with s-video.
