Any word on wether or not your were able to get that card working? I have been considering two different laptops for a hackintosh and they both have AMD graphics.


Acer Aspire 7750g which has a 6850M




HP DV7T which has a 6770M


Does anyone know if either of these will work? preferably the 6850M.
