I do not have a solution, but I can say I notice the same problem. I also have an iMac 27" I tried updating the videocard drivers but it did not help at all. I agree with the AMD rep: its probably not a windows issue but rather an issue with the drivers made by apple. Im not an expert tho; it's just speculation.
I found the following discussion very useful. Rolling back to the 8.661 driver fixed the 16-bit color banding for me!! Hopefully this driver has no other problems.
