I found this site which was recommended as providing great deals on all computer parts and they also sell a few built gaming desktops. This one below all looks fantastic. I would sell the graphics card instantly though and purchase a 980 or 1070 and also need to ask someone who works there what the deal is with the motherboard because it doesn't show one in the specs.
Other than that, does this look like a good setup to have to run P3D?
