It depends on your preferred refresh rate.

1080p (1920×1080) minimum Mbps:

30FPS 10Mbps
60FPS 20Mbps
120FPS 40Mbps

Latency is more important than speed with Maximumsettings game streaming PC's. Make sure it's below 40ms for the best experience.

How do I ping to check for latency?

If you are using Windows please
Go to Start > Run and type cmd. You can also search for cmd.exe in the Windows Search function.
Press OK to launch Windows Command. This is the default command-line interface for Windows.

Type ping maximumsettings.com
