yes, for viewport performance the quadros show better performance numbers cause their drivers allow them to utilize all their power.
but when it comes to rendering, all GPU based renderers I know of don’t care if it is a quadro or a gforce - as long as it’s cuda capable.
of course the hardware of quadro is exactly the same as geforce, just another cooler slapped on to it and much more expensive.
look at all the people building octane render workstations - they use lots of GTX1080 or GTX1080Ti and don’t care about quadro.
I would’t be surprised if nvidia made the decision to prohibit this by driver as well in the future.
nice that cycles devs made the effort to also make it work with openCL
