If you're planning on using an LCD monitor for games, you want to find one with the lowest response time possible. Most Samsung, Viewsonic, and Sony monitors have really nice image quality, but they have response times of 25-40ms... you want to find one with 20, or less. You should check out NEC monitors. I bought a 17 inch NEC monitor with a 16ms response time, and it works just as good as my old crt.
