I just did 373.xx
minimum install is driver only.
PhysX, if you play another game that uses.
HD Audio, if you wish HDMI sound thru your display.
FYI,
I discovered a process running as well. Called Nvidia backend +32. It googles as part of the GFE. I did not install GFE, and yet a high demand process/service was added/started. I disabled it in w10.
