Dual Video Card on PCIEX16 and PCI

[dextertrial]

Hello
I`m currently running this setup:
P7H55
2.81 GHz Intel Core i5
8gigs of RAM
Nvidia 660GTX 2gb

I`m using it for various graphics applications including lately DaVinci Resolve and I`d like to get a GUI GPU for it so it can use the full power of my 660 for the video processing,but my P7H55 is an mATX motherboard(I know,I know but I built this machine without the intention to hackintosh it at the time)so being the cheapo that I am I was thinking about getting a PCI Card ( GeForce GT 610 PCI 1GB ) and I was wondering if its gonna work with Mountain Lion ?

No, SLI doesn't work with OSX and doesn't work this way, anyway. Only option is a better single GPU.

This won`t be SLI ,both cards are connected separately without any SLI bridge and Resolve uses them separately one for the GUI and the other for processing

Hmm, not sure what DaVinci Resolve's capabilities are, but Google says two card are definitively possible under Mountain Lion. And a GT 610 will work out of the box with PCIe.

Now, PCI is another story, plus, the 660 Ti is more then 10 times as powerful as the 610, so performance benefits may be missing.
