I want to use the new mini for the 27" and it's gotten pretty good reviews from sites like the Verge. I don't game at all. The lag should be perfect. It does say something about downsizing 5k to 4.5k or something or maybe 45Mhz vs 60 which I don't know if I would be able to tell (but I love display quality). Anyone use this? Sounds like a perfect soliton for this problem. Will I be happy?
