Doesn't nvidia-settings show to which display the cards sync? Did you specify which card is to be used by the X server? Does it hurt to remove the GT 430? There is worlds of difference between a GT 430 and a GTX 960. When you compare these two cards, you may find that running the 430 isn't worth the electricity it costs, unless you get it for free or almost free. You may also get the impression that your whole desktop, or at least your web browser, is slow when you go from the 960 back to the 430 :) I think I'd just remove the 430 and see how it goes. If you're then happy with the performance, there's no need to put the 430 back.
