Anyone know the difference between all three cards? I know the 9700 is ATI's top of the line card, but how about the difference between the 8500 vs. 9000? The ATI 8500 was the old champ but it seems like the ATI 9000 is a consumer version of the ATI 9700. Does this mean the ATI 8500 is still better/faster or can the ATI 9000 hold it's own? I was planning to wait and buy an ATI 8500 once OS X 10.2 was released hoping the price would drop down but it seems like the ATI 9000 will be evenly priced with the ATI 8500. Any ideas or suggestions would be greatly appreciated ...
