On the Mac, there are no dual display video card conflicts; so if that's your platform, you are all set. 

With Windows, some single cards (particularly PCI Express cards) work fine; others don't register as two devices for profile assignment, or don't have two distinct slots for video card corrections (LUTs). 

With a desktop (you don't mention computer type, either) a second card will fix any issues (or the new card may run both correctly by itself, for that matter). 

With laptops, adding a card isn't typically an option. So for systems that can't handle two profiles and calibrations, a choice between them has to be made.  Calibrate the internal display, or the external.
