Hi everyone, Same as most of the people i encounter a trouble with the graphic card of my Imac 2010 HD6970. It died and for ever even if try to give her a new life by making a cure cycle. So i have to replace it by the same model or the best one HD6970 2gb, and i found some of them but not coming from Imac but other laptop like Alienware or Dell. Does anyone already try to put these models in Imac ? Does it work ? Because these kind of graphic card are cheaper than the apple one and easier to find. Thanks for your help.
