Question: Looking for a suggestion for a good used 27" iMac 2012-2015, based on reliability.
I know the 2008-2011 tended to overheat especially the GPU. It's my impression that the later 2012 to current models are better. Looking for a budget used 27" for lightweight stuff, just want a reliable one, so no flakey soldering jobs, no iffy power supplies, no overheating CPUs or GPUs. Doesn't have to be 5K Retina either. So, I'm thinking 2012 to 2015 should be cheap enough. Where there a lot of problems with some models to avoid? I'm sure somebody has a gripe in this time period, so I'm looking for trends, recommendations. Thanks one and all in advance.
