Your monitor is always capable of refreshing at 120hz, but that doesn't mean the game is able to display 120 frames for each instance that the monitor refreshes.
120 FPS lines up nicely with 120hz, but if your video card is only sending out 80 FPS, then you are only seeing 80 Frames each second, not 120. The monitor may be ready to receive 120, but that doesn't mean your system is sending that many.
Plain and simple if you want to really experience 120 FPS gaming, you need a 120hz monitor and a system that can pump 120 frames out. My system currently (see sig, it's not bad) has a hard time running games with max settings at 120 frames. However, if you turn down some settings like AA, filtering quality, Bloom, etc, you might see more steady 100+ FPS.
The trick is to find a middle ground where FPS and image quality match for the system you have. My old system, I used to just turn everything on low just to try to get more FPS =P
