    Possibly looking to get a new iMac. Both systems would have 32 gigs of ram. Price difference is not an issue. Heavy graphics and medium video work and looking for which one will give me the best performance.

    2011 vid card = AMD Radeon HD 6970M
    5k vid card = AMD Radeon 2GB R9 M395

    The 5k has a much better graphics card, that simple really, to be honest try and make sure it has at least a 2Tb fusion or SSD as well, that is the main issue with the iMac these days, the spinning HDD that comes as standard is a dog and ruins the performance.

    When you say graphics work, do you mean heavy 3d graphics? Or photo editing/graphic design? Because if you plan on doing heavy video/3D graphics work, i.e. 1 minute+ 4k compositions, neither of these is up to the task. You're really going to want a desktop with a decent GPU instead of the low-end mobile GPU's in iMacs. But if you only work with fairly short 720p or 1080p comps, or photos, etc. the 5k iMac will do okay. But for reference, the GPU performance of the 5k iMac is still only about half that of modern mid-tier $150-200 cards.

    As a side note, I'm also fairly certain Apple has had a lot of trouble with the 6970m, so I would avoid it entirely.

    If I work with 4K it won't be intensive. Simple cuts, dissolves, titles, etc.

    Graphics work is Adobe's Creative Suite. No 3D.

    I could go the PC route, but then that would take Final Cut Pro out of the equation if I want to use that instead of Premier for certain projects.

    Can't see a single reason to buy a 2011 iMac (great machines that they are, I have one) if you can afford a 2015 5k. But as noted above, make sure you get an SSD or a 2TB Fusion Drive.

    Give the 2011 a big miss. It is now yesterday's technology. Old USB2 ports, slower 7200rpm platter drive, inadequate graphics, slower memory.

    It seems the 2011 isn't an option as it's too dated now. Thanks for the feedback guys and gals.

    5k. I don't even know why the 2011 is in the mix as an option in this, as you're talking about an entirely different class of desktop.

    The indecision was mainly because of i7 vs i5.

    That's fair, but a 2011 i7 is trounced by a 2015 i5.

    With Apple not going all out with the last refresh, from what I've read, I wasn't sure if there would be much of a tangible power difference.
