I hear on the nvidia forums / guru forums that there will be a nvidia driver out before the end of the year, rumour but hopeful.
The drivers in question for AMD/ATI are "Preview" or Beta drivers, not yet ready for release. Nvidia already has two Beta drivers with Skyrim changes: 285.79 and 290.36. The latter adds in SSAO without having to use Nvidia Inspector, which I believe AMD/ATI GPUs currently lack.
The problem is, Skyrim gets rather CPU-limited at higher settings.
