I have the option from my company to buy a used
Mac (Retina 5K, 27-inch, Mid 2015)
3.3 GHz Intel Core i5
16 GB 1600 MHz DDR3
AMD Radeon R9 M290 2048 MB
More specs
or
iMac (27-inch, Late 2013)
3.4 GHz Intel Core i5
16 GB 1600 MHz DDR3
NVIDIA GeForce GTX 775M 2048 MB
More Specs
The 2015 is obviously a year+ newer model and has a Retina Display. The 2013 is .1Ghz faster. Im not sure if there are any other differences I should be aware of. Both are being offered at the same price.
