If you are playing FPSs such as Quake and F.E.A.R., I believe those two are good examples, and games with a lot of darkness, the LCD will have trouble displaying detail in darkness... Because LCDs have a single brightness at one time, they don't do so well with areas of brightness in a dark scene (like in Quake), but CRTs illuminate each pixel separately. If that's not too much of an issue for you, then LCDs are better by now...
