Borderlands 2 isn't out for Mac yet, but apparently is on the way. I intend to run the game(s) on the lowest possible settings. I have the 2011 iMac 21.5 (the base model). I'm sure you know the specs but it's a 2.5Ghz i5, and I fitted it with 32Gb of RAM. Will these games run smoothly on lowest settings on this rig?
