I disagree a little with the article Christopher cited. Rapidly moving images can “tear” or look blurred at 60Hz. Most of the time, I only notice it when watching a hockey or football game in HD, and the camera pans rapidly. 99% of the time, you probably won't notice the difference, but it can be distracting when you do.
A faster refresh rate doesn't really matter, according to this article. Here's the bottom line:
"First, you can't add detail beyond what is already in the source footage. Second, the source footage is never greater than 60Hz."
There's more detail in the article. It's pretty interesting.
