Back when I had CRTs, 60Hz displays were the older, less-common, cheapo option. I'm having a hard time remembering a CRT display that wasn't at least 75Hz (I believe this was the VESA standard for the minimum to be flicker-free), but most of the monitors I used had refresh rates in the 80-90Hz range. I remember a beautiful higher-end CRT that had a refresh rate around 110Hz.

85Hz gives you a frame time of 11ms, which doesn't sound much better, but is a 30% improvement over 16ms.

Before multi-sync CRTs and SVGA, 60Hz was not the "cheapo" option.

I don't think you can get a display slower than a TV, and they do in fact update at ~60Hz (or 50Hz, depending on region). Of course you're probably only getting VGA, 240p, or less in terms of pixels.
