Didn't see much in the way of improvements except for maybe the 58xx series. Here is the link never the less.

I think it'll be a while before we see major improvements with the 5000 series.
Yeah, that's to be expected I suppose. Still always seems that most of the catalyst updates are fixing bugs rather than optimizing for better performance. It's okay I guess. I just never have any of those issues that they mention in the release notes.
