The biggest problem with LCD panels with 1600X1200 resolution is that many video cards can't run newer games at those resolutions and still get high framerates.
I recently went on a shopping trip and looked at some fairly high end CRT's from Sony, Mitsubishi, Ilyama, etc, and even the best ones couldn't hold a candle to the better LCD's as far as image quality. In looking at them side by side it was evident that all of the CRT's were slightly mis-converged, slightly out of focus, slightly blurry... yuck.
I use my PC too long each day to let my eyeballs continue to suffer that abuse.
If the LCD I ordered doesn't do well in games then I will run my GF4 in dual head mode and use my 19" Samsung CRT for gaming.
