Run legacy driver and current driver at the same time?

[Tornadus]

I am currently running Nvidia Driver 342. This driver crashes on most of the games I want to play, but it allows all 3 of my graphics cards to work. When I update to the latst nvidia driver, only my GTC 580 works. The games I want to play work on the latest nvidia driver, but alas only the 580 actually works.(powering only 2 of my 4 monitors).

I am running:

2x Quadro NVS 290s
1x GeForce GTX 580

Is there any way I can get my two Quadro NVS 290's to work for basic monitor usage, while using my GTX 580 for gaming applications (with the latest nvidia driver)?

You can't have two different drivers running.

What do you need the 290s for? they appear to be... really bad at everything.

If they're only for powering displays, maybe picking up a used 580 or 570 off ebay to power the others would be the right solution. (as they will work with the same drivers)
