Okay, so I don't geek out this hardcore very often, but I make the occasional exception, and this is well worth it.
It's taken a while to figure out over the past several months, including 4 video cards, 2 operating systems, lots of drivers and cables, and a lot of clearing of desk space, but I finally found something that works.
Overkill? Maybe, but with my workflow, it will help out a lot. I'm thinking it will only get harder to work anywhere else but right here in my home office.
