Okay I flashed the radeon successfully, and then I updated the firmware to 126 (the latest on ATI's site)...works excellent..the only problem I have is it still thinks I have two displays hooked up when I don't..but games are awsome...even over the radeon 7500 in my laptop...and way better than the geforce I replaced! hope this might help someone else who wants to save half the price of a retail mac version!...cheers Mark
