Hello. I have a dilemma. I've bought mac mini mgem2. (late 2014, core i5 1.4 + 4 gb + HDD 500). Using it i've realized that it's not enough for me. Too slow when i use a lot of programms. And now i've decided to change it. I have 3 variants and i need your advice. 1) Buy new Mac Mini 2014 mgen2 (Late 2014 core i5 + 8 gb + 1 tb) 2) Buy used Mac Mini 2012 (Late 2012 core i7 + 16 gb + 1 tb + Samsung Evo 850 120 Gb) 3) Buy for example Samsung Evo 850 for my Mini Or maybe something else?
