It sounds to me like you might need that new driver to make it work properly, then. It looks to like the GHz cards and the regular cards are physically identical, with the extra performance simply being gained by software tuning with the BIOS and driver working together to make it happen - the 7970 is inherently very overclockable, after all. So, it sounds like enthusiasts will simply be able to "get" the GHz edition with a BIOS flash and a new driver. Nice. Tom's Hardware tested this card and found that the regular 7970 actually consumed around 5W less than the GHz card too, among other things.
