Blender not recognizing quadro 4000 graphic card for CUDA computing?

I am running latest version of blender on my workstation but for computing it is not recognizing my quadro 4000 graphic card.

I have another geforce installed which is not connected, it is showing that but not the current graphic card.

If I render will it use my current GPU quadro 4000 or the geforce one as the compute device? How can I make it use quadro as the main GPU renderer?


I updated my quadro drivers and it is recognizing it now in the system settings.
