Hi, I've done a lot of reading in this forum and i have learned alot about flashing PC cards for Mac Pro, thanks all! But there doesn't seem to be any consolidated info like there is for the 4870 and 4890. From what i can tell a few have been successful flasing the 5770 for the first gen Mac Pro. It would be great if those who have had success could post some relevant to info for noobs like me. Can someone link or post the roms? Also, list the cards you've had success with. I have a mac edition 5770 on order but i'd definately prefer to save 200 bones by picking up a used or new pc version and flashing it. I'd appreciate your help in doing so! Thanks!
