It depends on what you are working on as well. When Im doing UI stuff, I love having at least dual monitors. That way I can have the result GUI /web page open on one screen, code and console on the second. This lets me reload without switching windows or workspaces continually. When im doing backend stuff, I can have several consoles doing testing and also for example the design document open while working so i can glance quickly at it. In the end it comes down to what you do, and what you like. I now use a ultra wide 29" screen instead and it works equally or better sometimes. My second monitor only keeps playlists, IM and email open now.
