I am in the market for a new Mac, and am planning to get a iMac, however, recently I have seen that the Mac minis offer significantly better performance for their price. I intend to use the device for casual to moderate gaming and occasional video editing. I am wondering how much faster a Mac mini with the above specs would be compared to the baseline iMac. And also, how do Intel HD Integrated Graphics 4000 compare to Nvidia GEFORCE 640 M. Thanks! ---------- I am also trying to decide whether Fusion Drive would be worth it for my uses.
