The way I understanad the difference between the GRX & Quadro Series is the fact that Quadro are more for industrial applications for example when modeling a real product and you need to find out it's weaknesses and make a simulation which is mostly for engineering purposes and production of real stuff , etc. Of course here you are going to need very very precise and will need tons of polygons. Animation game development , etc, do not need to go that far it's optional so it may not be that advantageous to have a quadro as opposed to a GTX card where as he said there are more cuda cores each acting as a separate mini cpu and this is great for rendering along with RAM.
