I haven't seen this specific question asked before, so I thought I'd give it a shot.

The background:

I will be building a personal PC that will have to fulfill several functions, two of which include gaming (not anything super intensive, but gaming nonetheless) and running SolidWorks for work and school. While the GTX 750ti I have now works fine for my game requirements, I know I will probably have to get a Quadro or equivalent workstation card to run Solidworks.

The questions:

I've heard different things about running GTX and Quadro cards in the same machine; some people have done it, other people say it shouldn't be done. Is there a way to run both styles of card simultaneously? I've heard that with the newer generations of Windows, having two graphics card drivers shouldn't be a problem. Instead of hooking one monitor up to each card (for a dual monitor setup), is there a way to designate SW to run on the Quadro, while everything else runs on a GTX card?

I've heard of people running SW perfectly fine on GTX cards even though they're not "approved." For those of you who have experimented with this, is there a noticeable stability difference between the two different types of cards?
