I would recommend locking your FPS in games to a max of 60 . The massive fluctuations in frame rate can negatively affect your play by having jitters where 200 FPS becomes 70 FPS all of a sudden. The other thing to consider is you want your system to synchronize with the server as accurately as possible. By having an extremely steady frame rate, on  steady network connection, and the right network config you can help to maximize your synchronization over the network, for better hit registration (you click with your cursor over an enemy and the server interprets it as a hit and registers the damage) and so that your teammates don't appear to lag around as much, either.
Typically this can be done through the console, but every game is different.
