Break down gaming latency into network, server and display components.
Network ping is only one component: a 64 Hz server adds around 16 milliseconds regardless of connection quality. Jitter matters more than raw ping because the client must buffer for the worst case. Chasing ping below about 20 milliseconds gives little benefit when the server tick rate contributes more than the network does.
Network Latency
Total = ping + jitter + tick interval + frame time + half a refresh interval

Chasing ping below about 20 milliseconds gives little benefit when the server tick rate contributes more than the network does.
This calculator takes 5 inputs: Round trip ping, Jitter, Server tick rate, Client frame rate, Display refresh rate. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
