Some (if not most) GUI Git tools should do this, e.g. I personally use Git Extensions[1] which shows history and diff side-by-side. For what it's worth, features like that (along with, say, line-by-line staging) are the reason why I usually use a GUI client and only drop down to the command line when necessary.
