use DDU to wipe the video drivers off , reboot let windows see the video card and install win drivers, reboot, then reinstall manufacturer drivers. for the video card
DDU can be found here http://www.guru3d.com/files-details/display-driver-uninstaller-download.html
AWESOME! Thanks a ton for this script. Worked great, and upon running this and reinstalling drivers, only one graphics card is showing up.

Is your CPU benchmark score good? Do you have the latest BIOS update available for the motherboard? Apart from the benchmark giving a bad score for your GPU, how does it actually perform in games or whatever you use the computer for? Could be that Passmark is giving you a faulty result. Have you tried Furmark? Did you try to completely uninstall and reinstall the GPU drivers as suggested above?
You can find my benchmark scores
here. 3D graphics mark just skyrocketed after running that script and reinstalling. Still a bit under the 'average' for GTX970 according to PassMark, but still way higher than what I was getting before.
However, it does look like the original issue (detecting two graphics cards) is fixed.
As for your comments on performance ratings, it was scoring low across all benchmarks that I had performed. In-game it is doing well, but not as well as it should be. For example, even when playing a game like Rocket League, there will be full games where my FPS is sitting in the mid 50s. GTX 970 should be hitting 144+ constantly. Since this is my first custom built PC, I was so happy with the bump in performance initially, but after a while realized that I just wasn't getting the output that I should in games. Figured if I paid for a 970, might as well be using it all...
