There's a guy on the guru3d forums who has a pretty good rundown between the 8.6s and the hotfix. I've also seen both in action myself, and the performance on the hotfix drivers is worse than the official.
I think the main purpose of the hotfix was to improve crossfire and enable support for a few games, but I've seen performance suffer in several games on a single 4870 with those drivers.
Edit: Here's the thread I'm referencing. You'll need to scroll down to his second post.
