I run with a 22" Widescreen for my main, and a 19" regular with the 4 others on it. It's good enough for most tasks, but you really cant read the text on the 19" instances. I've seen a lot of people do 2x 22" Widescreens, and I bet that would be better. Alternatively, I've also seen people use 1 30" Widescreen to 5box on (I believe it has the same overall space as a 22" + 19"). 2 30"-ers would be sweet, but the most expensive option.
