well tbh you dont have a vast choice in the 20" market right now, this is improving, but the Dell is pretty good still. A lot of people find it fine for gaming, but it is not as responsive as modern TN Film panels like those used in the fast 19" market. There is the Belinea 102035W which is an improvement and uses a new overdriven P-MVA panel, but depending on the games you play, the Dell might be fine too
