I have a 15" 2012 retina 2.7Ghz/16gb/512/NvidiaGt650M.
It works swimmingly for my current needs(gpu is slow though - e.g. image classification tasks on xcode, however for me those are fun projects).
Battery is @80% health now, and one of the fans makes some noise(I dropped it on a hard surface from around 2 feet).... But I'll keep it for at least 1 year, especially with the latest Catalina is my thought for now.
