I've thought the same, have you considered the possible options of external graphics cards and bootcamping?

I think external GPUs are an awesome idea. I've not looked into hem recently, actually. They would be awesome for making a 15" MBP from 2014 more useful going forward.

unfortunately to my knowledge they work only with thunderbolt 2+ (ideally 3), not quite sure about 2014 models and their ports.
