your computer may be able to render something at 300fps or more, but the screen is only capable of showing 60 of those frames per second. so for every 5 frames your computer draws, only 1 of them will be shown. The rest are essentially unused.

Worse yet, when the computer finishes a new frame, it'll start sending that one to the monitor rather than finishing the frame in progress. That's what causes tearing and is the reason for using vsync.

Plasma screens have refresh rates in the hundreds, although I don't know much about the availability of them in smaller more "monitor-like" sizes.

Yeah they are getting better but it's hard to use plasma screens as computer monitors due to ghosting (since you can be idle on the same screen for hours on a PC).

Because those 120/240/600/whatever-hz TVs can't actually accept a 120hz signal, they just use (usually bad) interpolation circuitry to add extra frames. I don't think the electronics to truly accept a higher frequency signal cost that much more, I think it's more a matter of the manufacturers weren't seeing demand for such a feature before. Now, post-Avatar, it's probably going to be another stupid reason for a markup, like 120hz TVs in general.

Having had (and broken) a 120hz monitor, I can say it's definitely worth it, even if you don't play in 3D. Wait a few months and there will be more options on the market, hopefully driving prices down.
