It comes as no surprise that there's very little performance improvements when it comes to looking at the FPS. In saying that, there's a bit of movement for the HD 5850 in some areas and slightly more for the HD 5870. The main reason we didn't expect a whole lot from the driver was because the Catalyst team has probably no doubt been working hard on creating a stable driver for the HD 5970.

If you're a HD 5770 user we would recommend that you move off the beta and onto the official WHQL driver for the simple fact that it's an official one. If you're also on a HD 5800 series model you may as well make the jump; there's no negative performance effects in our tests and a few positive ones to be seen.
