It is absolutely critical. The 30-40% productivity gain per monitor is absolutely true.
My setups have included:
Three 19" screens at 1280x1024. This was uber productive. Reference/communication on the left screen, code in the middle screen, test on the right screen.
Now I'm running a 23" Samsung and a 27" Asus. I use the 27" to code and the 23" to read/test on. The 27" has a 1920x1080 resolution but larger type causes less strain on my eyes.
Where do I think I'm going to end up? Buying a 27" iMac and using it as a Target Display Mode for my next Macbook Air. I think I could do it all on one 27".
