Hello all, Forgive I know this thread is very similar to about a hundred others on this forum but I can't seem to locate one directly on point. I currently have a MacBook Pro from April of 2011. Is is 2.2ghz i7 quad core with high res display. 1gb discrete graphics and 16gb ram. My photography has really taken off and as I get more and more work (it's only a side job btw) I have found that I would prefer a desktop with a large display. I'm finally ready for an iMac and I'm trying to decide my options. The on sticking point is the processor - From I have read, it appears the i5 higher end model will be perfect for me but I can't help it wonder if I should upgrade to the i7 or even purchase an i7 refurb instead. Any thoughts if, after having a mobile i7, I will feel stifled by a desktop i5? For reference I use aperture extensively. The only other applications I use are the basics (web, email, word, iTunes) and occasionally handbrake (which I know does benefit from the i7 but I don't use it a lot to justify the i7 on that alone). Thanks for your help.
