Games at non-native resolution

[aevm]

It depends on budget. You could get a 27" 1920x1200 monitor (say, Samsung 275T) and a 19" or 22" monitor, and switch nVidia profiles between monitor #1, monitor #2, or DualView. That is, play less demanding games on the big monitor, play Crysis on the small monitor, or do programming+surfing+email+(maybe)watch tv/movies on both monitors.
