If doing online gaming, ping will affect how long it takes for a button press/mouse click to be seen on the server you are playing on, the higher the ping the longer it takes.
e.g. you line up some one to headshot that is facing away from you in a first person shooter and fire, if its a low ping you hit them or if its a high ping you are likely to miss. Or worse if its a high enough ping, what you are seeing is not what is actually happening and that player you are trying to headshot is actually looking at you and about to pull the trigger but from a different position and not what you are looking at. They have the ping advantage.
So a rough guide is if the server is in
UK, you want a ping to the server of 15ms if you are luck or more likely it will be 25-30 ms, as once you join the game 10 to 15ms is usually added on top of that
Western europe, 50+
USofA, best you will get is 100ms due to how they router traffic
20-30 is ideal with little or no lag
40-60 you have to start leading you shots if the target is moving
70-100 a fair bit more
125+ no point for a FPS that is just too high unless you are used to it
Note this doesn't really affect MMO's as much as you don't have to Aim in the majority of them, even in pvp. Then as long as the ping is lower than 150ms its fine
