My HTPC is currently an early 2009 Mac mini, 2GHz Core 2 Duo with 8GB RAM. It's starting to show its age running 10.10.5 (an increase in beachballing while it thinks about things) and it also has problems with smooth playback on some (not all) full-screen 1080p video. It flat-out doesn't have the power for h.265 video. Looking at the Apple refurb store I can pick up a 2014 mini with 1.4GHz Core i5 for an attractive price. At the risk of asking a dumb question, is that a worthwhile upgrade? Will it seem like it screams compared to my current mini?
