Don't look at the version numbers as it's been proven (including by me) in the past that driver versions from AMD with the same number are NOT the same. Quite often the file once expanded are slightly different sizes which is an obvious giveaway, but they also may be the same size. If you do a file compare of them though, you will find they are different. The difference is because the version numbers don't represent the actual build of a file, just a generalisation that the higher the number the later code wise the file is (although sometimes this isn't even the case!).
