From my experience, 27" 1080P looks great with console games, but is not so hot with PC games. I'd stay around 23" max for that. I would not have purchased my 27" monitor if I was going to use it strictly for PC gaming. I used it briefly as my PC monitor when I was in the middle of moving and the picture was noticeably pixelated when using a lot of applications. Nothing too horrible, either, but still noticeable enough that I was glad to go back to a smaller monitor.
