Dual (different) card setup

Tomorrow, I will build my new PC that I will be using primarily for CUDA development. It has a GTX970 to do the number crunching and I bought a simple N210 to serve alongside it as a display manager to avoid display failures when I mess up a kernel (which I will).

My question is how to set this all up driverwise. Will this all work out of the box or will I have to work some magic? Will the system at least boot with both cards plugged in?

Also, what should I do when I decide to play a game that needs to be rendered by the 970?

Thanks in advance for your troubles!
