The Quadros have higher quality memory (part of the reason they're so expensive relative to the performance) and are better tested, so in theory they're more stable. For the purposes of a visual effects workstation I don't think this is that critical. We recommend the GTX cards for our plugins. You just get a lot more for your money and the 980/Titan Z are just super fast. However, for a render node that's going to be rendering 24/7, the Quadros may offer some value due to the increased stability.
The high end GTX cards always perform better than the Quadros, as that's where all the new technology shows up first. Again, in theory, this means it's more likely to be buggy, but in our tests the GTX cards haven't been less stable than the Quadros. The newer Quadros (e.g. K5200) are reasonably fast but a Titan Z is going to blow it away for half the price. I wouldn't go so far as to say avoid the Quadros, you're just going to get more speed for your money with the gamer cards.
A note on the expansion chassis… the video cards seem to be harder to recognize from a software point of view. We've had a few reports that the Cubix Expansion doesn't work with our plugins and may not work with other apps or plugins. It _does_ work with Resolve and there are definitely folks using them, but if you're getting one of the chassis to speed up specific software, check with the manufacturer that the software supports the chassis you're thinking of buying.
Cheers,
Jim

Subject: [Avid-L2] Re: GPU for Resolve and MC
Once again I was told directly from the Resolve engineers the Quadro 4K was old news about a year and a half ago. They were all about the GTX series with it's additional Cuda cores. Are these Quadro K4000 etc... something new and different from the Quadros I was told to avoid by Resolve engineers? Is this something more about PC vs. Mac. When I went through this the Quadros were way more expensive than the GTX-680 and performed much worse according to the Resolve folks. Was I mislead or have things changed? At the time I was under the impression the Quadros were yesterdays technology and were being abandoned. Did I get this wrong?

The good news is you are in a PC so you have more slots to work with. Depending upon the card you pick and the power supply in your system, you might have to supplement it. I had to add an external power supply because my Z800 had the 750 watt power supply but some shipped with an 1100 watt supply.
As for cards you can go for Quadro K4000, K5000, or K6000. According Greg Huson get at least 4 gigs of RAM on the card.
