does running two displays on one GPU reduce CUDA?

I have 2 GTX 970s and one 24" Dell display and am considering to add a second display to the 970.

does this impact CUDA?

Hi, it does not.
You need a small amount of VRAM for the second display, on my system it is less then 100MB.

thanks for the info!

Just worth mentioning, I noticed when I introduced a second screen to my setup, the graphics card temperature went up a dozen degrees. not sure if this means its using more of the cards wattage or it actually uses more cores.
