I have tried searching and googling this but most posts seem to be back in March. At that time Lion beta was working with a 6870 unflashed. Now that Lion is out has anyone been using an unflashed 6870 on their Macpro1,1? 3 displays working? I currently have a flashed 5770 card working in my machine but wanted to look at 6870 upgrade. Any pointers appreciated.
