The biggest plus over my LCD over my old CRT is the radiation. the radiation being emitted from my CRT, along with my abusrd closeness to the monitor, led my eyes to go like this- 20/20 one year, 20/50 the next, 20/100 the third. i actually just got my lenses changed....i dont know now what my eyes are but i do know my perscription (for glasses) is -2 in each eye.
that was pretty off-topic. but yeah, for gaming, LCD's are better because of the higher resolution. the first time i turned on my monitor (Samsung SyncMaster 730B) I was like "whoa...that's really amazingly clear."
