As I wait for an M1 mini deal for my development box, I've become more curious about picking up an older mini. I'm uncertain though whether to look for a 2011 or 2012 mini. I like that the 2011 supports SL unofficially and Lion as well, but the 2012 has 4000 graphics and Ivy Bridge. Ideally I'll be getting the i7 quad version of either year, so I'm not sure how big of a difference there is in performance. I'm mostly concerned with how the GPU will handle using a 1440p or 1600p monitor potentially with a second 1080p or 1200p monitor to the side. I worry that 3000 graphics won't be enough but I haven't had experience with this GPU on the Mac side of things before. Just curious to see what people's thoughts are on this and if it's worth trading the OS support of the 2011 for the extra performance of the 2012.
