I ran into an old forum post on another website today with a 2010 picture of my first build. Here is my 2010 build vs my 2013.
My 2010 build was Matrox TH2G and GTX470 Tri-SLI with three Optoma EX525ST. My 2013 build is 7970 Eyefinity 2x1 with two Optoma GT720. Does about the same thing just more refined and more cost effective. Shows evolution of my screen designs over the years.
