Previous to the monitor I have now, I used to have a Liyama Vision Pro Master 455 19" CRT monitor ( I know it's not the best in the world, but when your down on money, and monitor will do
), and it served me VERY well for the years that I had it.
On that monitor, I ran most games at 1280 x 1024 and it looked superb. I think the real question you have to ask yourself is how much screen do I want to be looking at? I mean my old Liyama monitor could do resolutions up to 2048 x 1536, and so both the monitors can manage the same resolutions, and so like I said before, the question is how much screen do you want to see?
