the quote below is complete nonsense.
first of all, its 60 FRAMES/sec for 720p, not fields. a field would be just the even scan lines or odd scan lines of a frame. we refer to fields when speaking of interlaced video and frames when speaking of progressive video. also, if by "spec for 720p" you mean ATSC, or digital television, i've got news for you. 720p@24fps is also a legal size/frame rate for ATSC. 60p isnt really the starting point for anything, its just another legal framerate.
film is by nature softer than video, but bluriness of film or video is not done to make the video seem smoother. in fact, film is usually shot at 24p and the human eye can actually perceive motion artifacts at this framerate.
LCDs are not magic. the computer sends the framebuffer data to the LCD once every so many milliseconds. just because its not a CRT does not mean that the computer can transfer data to the screen infinitely fast.
yes, the application may be able to put data into the framebuffer at some ridiculous rate. but if you dont synchronize the framebuffer updates with the video refresh rate, you get tearing, as some parts of the monitor have data from one frame, and others have different data.
i'm not aware of any video cards that average multiple frames before finally outputting the data to the monitor, as suggested below.

Please, Please, PLEASE stop confusing the two. Gaming FPS and Movie/TV/FILM FPS are NOT the same thing.
60Fields per second is the spec for 720p, so obviously 60FPS is the STARTING POINT.
Now, the DIFFERENCE HERE is that in FILM, and TV... each field is slightly blurred... so everything SEEMS FLUID!
In games, NOTHING IS BLURRED... everything is rendered (each frame) exactly as it is to be displayed. While the naked eye may not be able to see more FPS, and the monitor might not be able to display it (technically)... it WILL display the combination of the fields (FPS) which will give each frame a little blur (180FPS = 3 Fields at once... slight blur)... similar to a regular SINGLE MOVIE FRAME...
And will thus make the game appear much more smooth!
