To dual screen or not to dual screen

We have a second workstation in the office that we're looking to 'tart' up. The machine itself will be getting a ram boost but the next question we're facing is whether to go for a dual graphics card and have 2 19" or 20" full (not wide) screen monitors or 1 23" screen. As it is only for our second, backup, machine it doesn't HAVE to be all singing, all dancing. Just interested in the general opinion.

Thanks

Personally, I would ALWAYS go for two monitors, whatever their type.

I second that!
Go with two monitors if you have the choice.

I just recently went from one monitor to two, due to upgrading to REVIT Structure.
It's wicked awesome!

I wish I had this set up at home.

Two screens makes life much easier.
It will seem like a pain to begin with, but when you have to go back like I did (god forbid) to one monitor, you really notice how much difference it made.
