As dummerjohn mentions you will find that the experience is variable.
Online gaming, e.g. CoD, Battlefield rely on stable reasonably low pings. The speeds required to actually play a game are actually very low .25 Mbps in both directions will be enough.
With a ping of 10ms you get better hit detection and a smoother experience, with a variable ping you will die sometimes even though you had ducked, or worse you will see people jump across the screen
