Invest in the tools that will allow you to work most effectively. Your monitors are your tools. You would question a carpenter who uses a hand-saw all day instead of a power saw to finish a job in half the time. Tradesmen of all sorts, mechanics, welders, plumbers, electricians, even landscapers, know that their tools are an investment. They allow them to work efficiently and do jobs they otherwise couldn't. I'm not going to tell you that a 2560x1600 is necessarily worth the extra money vs a 1920x1080. I'm telling you that you should decide what tool is best for the job, and THEN consider if it is a worthwhile investment. After all, you are going to stare at that thing 8+ hours a day. Most people spend a lot of money on "luxury" options for their car, which they may drive an hour or less per day. Leather chairs, upgraded radio, navigation system, tinted windows, larger engine, special wheels, you name it. These things cost far more than a nice PC and monitors, and you use them far less! $0.02.
