Two Graphic Cards /Second one not working

[digiman]

Hello, I have 2 graphic cards installed in the ASUS P7P55D E Pro, and running SL 10.6.8. The first PCIe slot has an ATi Radeon 5770,(driving the primary display), and the second PCIe slot has a NVidia 9500 GT. Aim is to use the second card to drive another secondary display, but anything connected to the 9500 does not get recognized. (I can run both monitors off the 5770, though). Any suggestions please to get the second card operating? Thanks

Yes, I am booting with Chimera, and both my graphic cards are recognized in System profiler. When I connect both monitors to the Primary card, the HD 5770, via DVI and HDMI, I am able to have dual display.
But when I connect even one monitor to the secondary card, the GT9500, it is not recognized. Thank you for helping.

I am having the same problem with dual 280GTX cards, I had them both working after doing the whole parent child thing in snow leopard.

Is that the only way to get them working in Mountain Lion.
