Monitor

Hey everyone, I'm in the market for a second monitor for my set up. Right now I just do all my work off of my laptop but really use the additional screen real estate. I want to avoid buying the apple thunderbolt display as it's a little out of my price range. Do you guys have any recommendations for a second monitor? I work a lot in Photoshop and do a lot of design work so I'm looking for something with great color accuracy. Also I want to play diablo 3 on it lol.

Thanks!
