No, as long as the software can handle 4 cores, the 15" models have far better specs for the money than the 13" ones.

2. It's a dual core machine. A quad core will give you better longevity.

My recommendation, go for the 15" MBP.

Disclaimer: I have the retina MBP (16GB, 2.7, 512GB) , a huge upgrade from an older 13" MBP.

I have the exact same machine as Jen and chose it for a very simple reason: Quad core. I would have preferred a 13" but when I tested my raw converter (Sigma Photo Pro) on both it turned out that the 4 cores of the 15" models (retina or not) finished the job in almost precisely half the time of the dual core processor in the 13" model - even if the 13" had higher clock speed.

In my testing with Aperture and 21MP 1Ds3 RAW files, the 2.3GHz quad i7 and 2.7GHz quad i7 were 30% and 50% faster than the 2.9GHz dual i7 at exporting adjusted JPEGs. I shoot about 1000 shots per event job and deliver about 300. For me, this speed difference amounts to only about a 20 minute time savings out of 4-8 hours of postproduction, so I went with the 13" 2.9GHz dual i7 for portability. Any differences in responsiveness are barely perceptible, and the 13" has no trouble keeping up with fast-paced tethered shooting. I used some of the cost savings to bump RAM to 16GB and replace the optical drive with a 512GB SSD. The result is a pocket rocket that's 50-100% faster than my old 8-core Mac Pro.
