CRTs are still unmatched for gaming. Aside from input lag, they don't degrade low resolutions the same way that LCDs do. For the longest time I stuck with a 19" flatscreen 4:3 CRT that did 170Hz at 800x600, an absolute beast. As a kid I'd lug it around to QuakeWorld and Counter-Strike LAN tournaments.
I've gone through a bunch of high refresh rate LCDs since, but nothing has matched the perfect hand-eye sync of a CRT running at high FPS and high refresh rate with a 1000 Hz mouse, zooming around dm3 in a complete state of flow.
You kinda forget how low latency feels like until you relive it and thinks 'oh ye this is how it should feel like'. Like the reaponsiveness of a PS/2 keyboard.
