Is it possible to use both an integrated GPU and a PCI-e nvidia card?

[Inception]

I have a motherboard that has HDMI and VGA out.
I also have a Nvidia 8500GT card in it. Will it be possible in any way to make the computer give me a picture on four screens simultaniously?
How do I really manage video cards in f10, i can't seem to find any menus for it..
Or do I have to switch motherboard and get a Crossfire solution? Or is a pci-e + a pci card a viable solution?

Still haven't figured this one out! Help! : o

On my nVidia mainboard the onboard 6200 is automatically disabled by the hardware when you put a secondary graphics card in the PCI-e slot. There's nothing you can do in Linux to enable it, it's a decision made by the manufacturer as far as I know.

Oh.. I can re-enable it in my BIOS, where I can switch primary adapter from PCI-E to UMA.
I have an AMD RS690 mainboard.
My plan today is to try and edit my xorg.conf file manually.. Listing the devices and the modes.
