For me, dual monitors are a must. Just my preference. I cannot work with a single monitor no matter what the resolution is. One advantage of dual monitors is that if you ever have to do screen sharing, you can quickly hide anything on the other monitor that you don't want your clients to see while still being able to refer to it. Same goes if you are recording your screen/screecasting.
