I ordered a refurbished 2015 1.1GHz/8/256 machine last week. So far I'm happy with it, and at $929 was a reasonable price. However, I still have 7 days to decide if I want to keep it, and I'm wondering if it's worth the extra money to get the 2016 instead? Most of the benchmarks show the 2016 to be faster, but not my a huge amount. Some of the graphics benchmarks are significantly better on the 2016 from what I've seen, but I'm not editing 4K video on it either. So I guess I'm just wondering if anyone else has had to make this same decision, and if you thought the 2016 was worth spending the extra coin on or not. Thanks!
