Where can I find the most popular facebook apps?

[Ryan M]

I'm doing a little research of social network gaming apps. Just curious if there is a place that keeps current information on the most popular gaming applications on facebook.
I know sites like zynga and snapfish have very popular games like mafia wars, farmville, farm town and resturant city.
If you know of any site that keeps or knows count of the numbers of users using an app let me know.
