How big is big enough screen for CAD work?

There are some big screens on the market but there's one that stands out. With 43'' diagonal viewing area and 2880×900 pixels the manufacturer claims that the curved design of Ostendo's CRVD screen engages 75% of human peripheral vision. Perfect for that next pet CAD project.

Ok, so it's probably better for gaming (or really big Excel sheets), it costs $6500 and is only available in the US and Canada but I couldn't resist a little gadget lust :)
