I'm in the market for an editing machine and I'm in a weird conundrum. Here are the 2 machines I'm looking at in my budget: 27 iMac 3.2ghz i5 cpu, 16gb RAM, 1GB GPU, Fusion Drive vs Retina MBP, 2.4ghz i7, 16gb RAM, 1GB GPU, 256GB SSD I'm going to be using Premiere and After Effects on this thing. I don't *need* to be mobile but it would be nice, I don't *need* a 27" screen but it would be nice. So with the whole desktop vs laptop a non-issue, which machine would you guys recommend? It's hard to get performance comparisons on specific upgrades. Thanks!
