    I'm purchasing a new 27" iMac and am putting a tb ssd and i7 processor in it. I will also be maxing out the RAM. My questions is do I need to upgrade the video card too? I will never game on this machine, but will use it to edit pictures in Photos and edit some 4k video in iMovie that I take with my 6s+. I would rather put the $250 towards Apple Care and Ram, but want to make sure that I'm not missing out on something. Please Help!

    I'm on the same boat! I use Lightroom instead, and will be using iMovie for the 4K videos coming out from the 6S Plus... will never do gaming though!
    I think I could save by going with the i5 with less heat and noise (and maybe update CPU down the road?), but the GPU is soldered and we need to make a choice

    Anyone have any idea on the relative difference between the 3 different 2GB Radeon R9 options?

    M380, M390, M395

    Waiting on some info as well to pull the trigger.. Although I might go i7, M390 for lightroom use.. I think its more than enough. Gaming I do on my PS4 and Xbox one

    If Apple is using standard PC GPU names and if TechPowerUp database doesn't lie, the iMac has these chipsets:
    • M380 = re-rebadged Cape Verde (aka HD 7770). LMAO, this is 2011 era stuff. Costs around $50-$60 as PCI card.
    • M390/395: Unknown, I guess 390 is Pitcairn (HD 7870) and 395 is smaller Tonga (R9 285)
    • M395X = Rebadged Tonga, same as M295X in last iMac
    So, having a look at last years benchmarks should reveal what those 'new' GPUs can do ;)
    Well, except the M380, this will be even slower :D

    No real surprise though, AMD doesn't have anything else to offer. The iMac would catch fire with a Hawaii card installed.

    Do not cheap out after you're almost all in. Get the 395x (according to apple 3.7 Teraflops versus 3.5 for the previous 295x, whatever that means). Upgrade the RAM yourself later! You can get two 8GB sticks (16GB) for less than a hundred bucks, install in two minutes, and have 24GB RAM.

    IMO, when you're already spending 2-3k on a new computer, go ahead and get the better graphic card. No reason to cheap out at this point.

    I meant to say that I would be maxing out the ram on my own. There's no way I would pay Apples crazy prices for it. I just have a hard time spending $3500 on a computer when I could save $200 by not getting a graphics card that I'm pretty sure I'll never use.

    Same boat. With my config (i7+512ssd) I could save $350 USD by going to the middle M390 model instead of upgrading the top M395 model to a M395X.

    Am I right to assume the following correlations?:
    M390 = same tier as M290
    M395 = new tier/choice
    M395X = same tier as M295x

    Which begs the question: how much of an improvement is M390 over the old M290?
    Although, going from M390 to M395 is only a $70 USD upgrade for Aussies. Much more reasonable, but is there a point?
