Because your graphics card will live longer and consumes less energy when you lock your framerate. Why do you want to torture your graphics card with for example 120 FPS, even though 40 FPS is fast enough for your game?! wink
The framerate you use for your game depends on the type of your game. Only if you use very fast movements in your game (for example in racing games) you should use high frame rates.
