While I agree with Sirheck that the GTS-320 currently does well at 16x12, if I were buying a new monitor I'd be looking at a widescreen instead of 4:3 and that would also give me the benefit of 1680x1050, which would be a little less strain and still look good (better IMO I prefer widescreen when possible for LCDs). I'd say instead of the 204B get the 204BW or the 216BW better still.
The biggest problem will be future games where we don't know the performance on games like Crysis.
IMO the WS is the way to go, better FOV and slightly less pixel load without compromising image quality.
