Hi: am planning on upgrading my PC with another 980 card to support my new 3X1080 24" panels. Also I wanted a fourth (on top) accessory panel but I didn't want to connect this panel to the SLI setup. So can I actually do such thing like connect the accessory panel to the built-in VGA in my Z97-A motherboard or put a cheap card in the PCI port as a third card but not connected to the SLI dedicated for that accessory panel.
