I have a Macbook Pro 8,2 with the Radeon HD 6770M GPU. It's two and a half years into the 3 of Applecare and so far it has been unaffected by the reported problems with this model. I think this could be because I run Gfx CardStatus and force the integrated GPU only to be used, unless I'm running something graphically intensive like 3D software or games etc. Recently I've taken to plugging it into my 30" monitor which can only be driven by the AMD GPU and I wonder if I'm inviting problems. Would like to hear from people who have been pushing their Macbook Pro and AMD GPU significantly for a long time and haven't run into issues. Is it inevitable that the GPU will fail?
