I took the printout to a local computer repair store and he is going to build me it for the same price. He did make recommendations as to the video card and RAM though. Instead of the Titan he offered options for the 970 and 980 that will work just fine for me and save money.

I found an image at nVidia that lists Relative GPU Performance

My current 680 card works great for what I use it for so even a slight upgrade should keep me happy. While it shows the Titan X is twice the performance of my current 680 l will probably get the 980, the 970 seems it would be too small of an upgrade.
