In my experience the Quadro graphics cards don’t function any better than the much, much less expensive GeForce cards. If you ever switch to something like Bunkspeed, which can render off the GPU, you will get a lot more bang for your buck in terms of CUDA cores, the main driver of how quickly and effectively you can render off the GPU. I run dual-SLI GeForce cards in lieu of a Quadro (for Solidworks, Rhino and Bunkspeed) and couldn’t be happier.
