I have a 2 hour time period to clear customs and catch my connecting flight later on this month in Atlanta. I am able clear customs in Dallas in an hour including hopping over to another terminal so I can't imagine it will be that difficult in Atlanta. They do have a tram system of some sort to transport you quickly based on my research.
