My input may not be so helpful since I have a Dell 30", but I set most games to 1920 (with my older X1900 card) and am quite happy with the results. Although if you already have a 24", it's good to realize that the image quality will actually go down a bit (scaled image vs native) although obviously the size/immersion will increase. I'm gaming a little these days on my 24" as I'm in the middle of a move and it's not a massive difference. In terms of screen real estate in productivity, it is. 30" is worth-while, but if you already have a 24" and will game at 1920, then for mostly gaming, it's probably not.
