i'm curious which of these is the better buy (from MacMall)
"old" 15" rMBP w/ 2.6ghz i7, 16gb ram, 512gb ssd - $2600 "sale" price
"new" 15" rMBP w/ 2.4ghz i7, 16gb ram, 512gb ssd - $2694
"new" 15" rMBP w/ 2.7ghz i7, 16gb ram, 512gb ssd - $2794
I'm not aware what differences there are in these machines besides a small bump in the CPU for the new models
