So, a little background: I work and freelance in the marketing/creative industry, mostly editing photos, video, audio and graphic design (i.e. heavy use of Adobe CS). Occasionally I do some basic 3D work in Google SketchUp for clients (museum/exhibit layouts). The MacBook Pro I've worked on for the last 7 years has been on its last legs for far too long, and I really need to replace it. Unfortunately I also have a poor post-grad budget sub-$2,000, so I'm wondering if I'll get more bang for my buck with a new 21.5" iMac (my workspace won't physically accommodate the 27" anyways), either the 2.9gHz or 2.7 with RAM upgraded to 16GB...or else, a used 2012 Mac Pro (perhaps similar to this), possibly putting a little work into upgrading some of the components in the near future. I've done some research, and the benchmarking tests by BareFeats [1, 2], although a bit tangential and outdated, potentially point favorably to the Mac Pro for my uses. I certainly like the upgradability of the Pro (I upgraded the RAM and hard drive in my MacBook several times, so in comparison, the Mac Pro looks really convenient), but honestly specs and all are not really my strong suit, so I'm feeling very uncertainthoughts? Thanks.
