I've been using a maxed out 2009 MBP and need to upgrade. I'm considering all options - 12" MB, MBP retina, or possibly iMac. I'm sure they are all far superior to what I've been working on, but I just want to see by how much. Can anyone recommend a site where I can compare stats, benchmarks, etc against each other, including my older 2009 MBP? I'm leaning towards the 12" Macbook because of portability, but being 1st gen concerns me, the whole 1 port/dongle issue, and possibly underpowered- as I'll be using photoshop, movie editing, and connecting to a 1080p monitor for the majority of its use. But if it does leaps and bounds over my 2009 MBP, then it might still be in the running. (Plus I like the black option, and I miss my Black Macbook) I appreciate any help. Thanks!
