It matches the refresh rate of your own screen. Disabling vSync on it's own is not considered cheating, however, if you want to do that you'll have to use an external program like Dxtory to limit your maximum framerate and make sure it doesn't go above 160. Setting the max fps to 120 is always the safest bet.
Actually, I was referring to the refresh rate setting of the screen, not the frame rate. Your frame rate limiting advice is helpful, anyway.
Every display has a list of supported resolution and refresh rate combinations. Take my 3D LCD, for example. At 1920x1080 it supports refresh rates of 50, 59, 60 (technically the same as 59 due to rounding methods), 100, 110, and 120. How does the game choose which rate to use?
For those who didn't know, what V-Sync does is delay all screen redraws until the monitor starts a new vertical sweep. This ensures that the image does not change mid-sweep, causing visual tearing distortions. This has the side effect of limiting the frame rate to no more than the refresh rate of the display.
