2. South Korea

Online gaming sucks up a lot of bandwidth, and there are few nations that love their games more than South Korea. It is home to several gaming competitions, such as World Cyber Games, and has entire television channels devoted to "electronic sports."

The average peak connection for the country was 48.8 megabits per second. And broadband, as in several of the top-ranked nations, is relatively cheap, too. People in Seoul can get 100 megabit-per-second lines for $31.90 a month, the report said.

"The pricing there is way more affordable," Belson said.
