This is an amazing website! Finally a way to find out for sure what kind of bandwidth you're really paying for.

This website allows you to test your own upload and download bandwidth/ping speeds for a number of servers across the country! I would think that this would help online gamers a lot because you can find where you get the best ping/latency from servers, and as a result, connect only to servers that are based in those regions. This leads to a much better game experience, in most cases.

Definitely check it out.
