My parts arrived and I am happy with the setup. Now getting the full 60 FPS on main screen and 20 FPS on all slaves, with plenty of power to spare.

The gigabyte board, i7 cpu, and 16 gigs of ram. I used my existing GTX 465 graphic card and SSD hard drives.

It may be time to upgrade the graphics card. I couldn't use SLI even if I wanted to, since the computer doesn't recognize the one in the x16 slot, only the x8 slot.
