Need Support 2 screens, 2 cards

Hey im asking for a little help on this one. I have a Gateway 500X with a integrated video card. After needing higher graphics i switched to the NVIDIA GEFORCE FX5700 LE. Now. i got a stupid monitor that came with it flat screen and then i got another one, NOW cutting to the chase. I'm tring to hook up both monitors as one which ive seen done, which is prolly easy to do im pretty techy, just not in this area. SO, when switching to the plug in NVIDIA into the PSI slot in order for it to work i had to go through and cancel out from reading only from the computer, so integrated disabled. So now i wanna set back up 2 screens but theres a problem running off the PSI slot theres only 1 plug in for a monitor other then the integrated which im more then welcome to using,
Is there a way to use both video cards in sync so i may duel screen this baby, because im pretty sure it would work. The How is my question, so in closing any help or leading would be appreciated along the way. Please contact me here and on my aim which is Ph4nt0m Phr34k13 Haxor much sorrys.

Thanks for any help given
