Can you mix Quadro and GeForce?

[Deathray2K]

I recently got a 3D Vision set up, and I'm really loving it, but I'd like to be able to use it in Cinema 4D as well so I can get a better preview when I'm doing stereoscopic renders. This however, needs a Quadro card to enable 3D Vision Pro, so I was thinking about picking up a cheap one just for that. But I still want to play games as well of course, so I was wondering if anyone knows what might be involved in switching back and forth between those two.

Another factor is that my motherboard only supports PCIE 3.0 with IB, but I have a SB processor, so installing another card would take me from PCIE 2.0 x16 to x8. Anyone have an idea of what sort of performance hit my GTX 770 would take from the lower bandwidth?
I have a 2600K so I'm sort of reluctant to upgrade to Ivy Bridge knowing I wouldn't see much of an improvement, but would it be worth it for the PCIE bandwidth?

The main problem is drivers.Quadro drivers are different from their geforce counterparts, you can install them and sometime they are smart enough to figure it out but you can have some issues as well.

Well I've read some mixed reports on that, but nothing recent really. What I've read (from 2011 or so) is that sometimes the quadro drivers will detect the GeForce card, and disable the Quadro features, and the only way to get around that was by disabling the GeForce card in the device manager. On the other hand some people were saying that they had that setup and it worked flawlessly without having to disable anything.
So I don't really know what to expect, and don't want to spend a couple hundred dollars on a card that won't work reliably because of bad drivers. =/

Anyone have more recent/reliable experience with this sort of setup?
