Just saw Tweakers Australia have posted a ATI Radeon driver comparison! Here's a byte from their article:
The driver comparison compares the performance of the 3 latest ATI reference drivers. Don't get these confused with the drivers designed for the 'Built by ATI' cards, as these are updated more frequently than the reference versions. Unfortunately, most people who can actually afford a Radeon 8500 settle with the 'Powered by ATI' models - therefore a reference driver must be used. 7.60, 7.67 and 7.68 are the versions we will be looking at, where 7.68 is the latest driver only just recently released by ATI.
