I'd gotten the 3 widescreens for work, the desktop room is fantactic. 4:3 / 16:10 / 4:3 is nice combo too, had it for a little while. Only problem I have with 4:3 on side screens is sometimes it can be a pain when you move a window from centre to a side screen and have to resize it. 3 x 16:10 is a very wide resolution, some of the times when I'm working I'll turn one off. If your just getting them for gaming then 4:3 / 16:10 / 4:3 could be a good way to go. It's all personal preference in the end really.
Actually have money for the high resolutions just never turned them on, did just now.
