    Thinking of buying the cheapest 27" 5k iMac and upgrading the 1Tb drive to a 2Tb fuison (as per the advice from many of the experts here!). I will be sharing this computer with my fiance (so often two accounts running and switching back and forth), aperture (maybe lightroom in the future), a very occasional photoshop and iMovie, browsing, email and some video format converting. If it is powerful enough I might run parallel as well at times for the better MS Excel in windows.

    My key concern from my previous late 2009 21" imac (lowest end spec) was that using aperture to edit RAW pictures (Canon 6D, 25-30mb usually) has gotten really really slow and my main goal is to have a much more fluid editing experience. Also I want to ensure running two accounts constantly in OS X is smooth. I also plan to use this computer for 5+ years. Is this spec good enough/too much for what I want?

    Summary
    27-inch iMac with Retina 5K display
    • 3.2GHz quad-core Intel Core i5, Turbo Boost up to 3.6GHz
    • 8GB 1867MHz DDR3 SDRAM - two 4GB (maybe upgrade this elsewhere later)
    • 2TB Fusion Drive
    • AMD Radeon R9 M380 with 2GB video memory
    • Magic Mouse 2

    Sounds like a good choice, The only thing I would add is some ram from OWC and you should be set

    I would suggest spending $100 more and buying the mid version instead. From what I have read on here the graphics card is twice as fast in that machine, which might help when editing RAM photos and help with longevity.

    In CAD terms it is nearly $200 more but I have heard this before....anyone can elaborate a bit more on this? I don't know too much about graphic cards - first time having a computer with a dGPU.

    Check out the bandwidth /interface differences in this table:

    Translation: twice the pipe size for your pixels. And depending on what else you might upgrade like an SSD, it's only $100 more - net

    I agree with the others, if you can swing for the GPU upgrade, I think you'll be better off. Check out if you qualify for student pricing or look at the refurbs as that might be an option to save some money.

    That table is for desktop cards. The iMacs use mobile video cards, which are not as powerful. More frustratingly for spec-hunters, the macs use configurations which are not found on the PC side.

    I'd recommend 16Gb of RAM if you really want to future-proof this machine. Especially when considering the cost you're putting into it.

    The 27" iMac has upgradeable ram so he can go to 16GB later if he wants. 8GB is fine now for most needs.

    At the same time, the GPU, CPU and the SSD are not upgradeable, so ponying up .. CAD240.. to have Apple put in an extra 8 Gigabytes takes money away from other, more pressing, and more permanent upgrades.

    yes this is the plan...no way i am buying ram from apple.
    yes I am not so concerned about ram for now as I can always upgrade it for cheap by myself.
