Second graphics card for panel only

I am using Prepar3D with two (but soon to expand to three) monitors for the main outside view, and another monitor for the 2D panel. All of these are connected to my main video card (GeForce GTX 980). However, the built-in nVidia Surround feature with bezel management assume all monitors will participate in the 'surround', which means the panel monitor is disabled.

 

So I am hoping that a second video card will allow me to attach the three main outside view monitors to the GTX980 with surround and bezel management, and attach the panel monitor to the second video card.

 

Anyone have experience with something like this? Or, recommendations for that second video card? I assume something fairly basic will work (about $100)

I run 2 monitors from my GE force GTX460 and my gauges monitor to a GE force 610. Paid about $60 for the 610.

Thanks - I found a cheap 610 online and moved my panel over to it, works great. But then I discovered it WAS possible to run nVidia Surround on two monitors and not the third, from one card (just needed to re-enable the third from Windows). Oh well, a little extra GPU power won't hurt... maybe now I should see what happens if I try adding monitors for a left and right window too! I might *just* have enough ports....
