Ok, makes a bit more sense now after reading up on them. Still is there any reason that the W4100 wouldn't perform as well or better? It's less expensive and has 4k support in case I ever decide to upgrade to 1 or more 4k panels. The only negative I see is that it has a fan and a higher TDP(neither are a issue in my case; my workstation has plenty of power and airflow).
If you don't need 4 displays and can survive on 3, an AMD R7 250X can drive 3 displays and do well in games if you would play anything. As soon as my new one gets here (my first one was DOA) it will be driving 3 displays.
Thanks, but I gotta have my 4 screens. I don't need any gaming performance on this machine; it's strictly my work computer. I have a gaming rig at home with a 4690k and a gtx 980 so I'm good in the gaming department.
