I would appreciate any help.

I have a 560ti and a 660GTX. Is it possible to have both cards installed on my sli motherboard,
both installed with different drivers on two different win7 OS with two hdd?

One OS should boot the 560ti with this specific driver (275.33) and the other OS should boot the 660gtx with it's driver(3xx.xx). I have both OS on different HDDs and i select them by Boot menu.

The problem i have it's that i must use this specific driver (275.33) with only this player PowerDVD 12 Ultra (v12.0.1312.54) in order for my 3D setup (3dvision+LG2363D) to run without crashing when watching 3d content.

For almost 3 years i have literary tried every driver from nvidia from 280.xx to always the newly released, every fix and every combination of PowerDVD and TMT, for the crashing. For those 3 years i always come back to the old 275.33 drivers (that's why i bought my 120hz monitor and 3d vision kit), so with that old drivers i can not use my pc for gaming unfortunately :(

In order to use only the 660gtx i must use a driver that support it (from 306.23 and above) but the driver must be the 275.33 so that's why i must keep my old 560ti on a different OS/hdd/drivers setup, so i can play 3d content on that setup.

Thank you.
 
Solution
The OS will see both cards if they are installed and will then need a driver to run BOTH cards, for what you are trying to do you will only be able to have one card installed at a time and then swap cards as needed.
