I'm a designer and animator who's currently got a 13" Macbook Aluminum (used mostly for design and light development work) and the latest revision of the Mac Mini, dual 2.6ghz with a Fusion Drive. I'm looking at getting rid of the Mini, which is reasonably capable but won't ever be confused for fast, and the 13" MB and replacing them with a MacBook Pro that I'd run mostly in clamshell mode connected to an external display or two. I don't do a ton of heavy rendering/simulation/effects, mostly character animation and some light modeling and rendering in Maya and Modo. I'm considering something like the 15" 2.7ghz with 16mb RAM and the GT650M. Any thoughts, ideally from folks with firsthand experience? Thanks.
