Agreed -- I find that a single large high-res display works better for my purposes. 32" at 4K is exactly right for three side-by-side 1280xY windows, which means that browsers will display full desktop-sized sites. Text isn't too small with the 32", so no scaling required. Divvy makes window management much faster, with little mouse interaction required. I have two 27" 2560x1440 displays at work, but I find it counterproductive to look side-to-side constantly to see what's on the other screen.
