I have a mid-2012 2.6GHz quad i7 Retina MBP (then top of the line). Now I'm looking to upgrade, and since I got an MBA now it rarely goes outdoors - it's more like a stowable desktop now. I'm considering eitber the current top line MBP (2.3GHz quad i7 I think?) And the current top line 21" iMac (2.9GHz quad i5?) Question is - will I suffer a processor performance hit on either buy? The rMBP has a clock speed hit, the iMac has a class hit to i5. I actually want an i7 iMac, but they're not available in my country. The heaviest thing I do is really just the occasional StarCraft 2 or F1 2013. Other than that it's iWork or web browsing or some other.
