Hi, My 2011 Macbook Pro has a broken GPU ('Radeongate') and I want to move on to a MacMini, but don't want to splash out too much money. Looking at a used 2011 MacMini model, which has an AMD Radeon HD 6630M built in. Is the AMD Radeon in that MacMini prone to failure, i mean: is this a "known problem" similar to the 2011 MBP? I'm thinking it may be wiser to go for a Mac Mini with built-in Intel 3000 graphics ? Less performance, but longer-lasting right?
