    I wanted to start a new thread to get as much response as possible.
    Also i should point out this is not just hate apple thread and it concerns Only Imac 5k 2014-2015
    I own a lot of apple products and im pretty happy with all of them so far. (i even liked the new 2016 macbooks with touch bar and not really getting the hate they get..especially about missing ports)
    Also i believe that i have every reason and proof"s to state that imac 27 5k has MAJOR design flaw.
    Let me start with the less important one.
    My specs are
    imac 27 late 2015
    intel core i7 6700k
    32gb ram
    ati r9 395x 4gb
    1tb ssd

    The less important but most irritating issue is the ati drivers support.
    Tot only, that unlike nvidia, they require separate drivers for bootcamp windows, their drivers are crap and until recent updates, there were a lot of crashing issue and very poor performance. So i waited.
    no crashes As of today but i cant simply run a lot of latest games because they require new drivers (16.20)to run an application and ati .just like old times. dont have those drivers for imac. The latest supported drivers are 15.30 .This is really irritating.

    SAme issue that stoped me from buying 2014 imac retina still exists 3 years later!!!!Holly molly i could have learn and code my own drivers by now ! As of today im willing to overpay a lot but i will always and forever avoid ati.
    Ok ,whatever.. Mac are not for gaming as the say..Even when equipped with a powerful but useless gpu.
    Moving on
    The second issue is based on a long and dedicated data collection of imac gpu failure equipped with ati cards.
    They all overheat and fail eventually..ANd by all i mean almost like 84%.
    And im going to go even further and say the r9 200 series and 300 series will /eventually. die,like 99%
    Thats of course if you use them under load. Just browsing and watching movies wont count.Those will live.
    The major design flow that i was saying is that this cards overheat a lot.Under load i get from 90-105C
    and thats with modified scalped processor and liquid metal thermal paste!!! I have like 10C better cooling in idle or minor load but as soon as something heavy runs i have no difference in temperatures before or after liquid metal.. THis oven cannot be stopped )

    Thats a lot and shortens the life span of a card to.Thos card will die. For some its 3 month for some its two year.There are exceptions but rarely id say. its a slow death but a bit faster then 2011 models.
    I dont know why apple decided to go with ati AGAIN (like 2011 models haven't taught them anything)
    2012 -2013 models with nvidia were flawless. There were issues of course but gpu related were more of an exception and not that common unlike new models with ati cards.
    Any way .those are my thoughts.any opinions matter.
    PS. of course im selling my imac and i will avoid it until i will see nvidia gpu in them.IMHO

    I use mXdrivers.com to download and install the latest ATI Crimson drivers for Windows 10. Now that they have their own self-signed certificate, it's even easier and the overall experience is much better.

    As for GPU longevity, I had my R295X for a year and my R395x for a year and they've been fine. But hey, that is what AppleCare is for, anyway.

    I'm pretty sure modern computers are capable enough of handling high temperatures without damaging components. I also dont see apple going for nvidia anytime soon...

    Those temps are normal but unacceptable. I get that with my iMac too.

    Apple is a very stupid company when it comes to priorities. They get off on making their products thinner, at any expense possible. Even if that product is a desktop which literally can only be negatively impacted by becoming thinner.

    Apple prioritises for the largest number of consumers, if that's not you buy something else, not their problem or ours but yours for buying the wrong kit for your usage.

    thanks i definitely will try xdriver.com hope it will help but still why do we have to invent things ? isnt this ati/apple job?
    Again about longevity...the thread about imac 2011 gpu is right here. I guarantee its going to be the same thing. Also as i mentioned it does depends o lot on how often and how long do you load your imac with gpu intensive work .
    I know this by the same pattern of behaviour of the card under heavy load. It acts exactly the same as 2011 models..Gets to hot to quick then drops to fast. This ups and downs is to familiar .Nvidia cards dont have same issue.

    Also has nothing to do with thinnes,pleanty if space in there,and again slim imacs with nvidia dont have this problem (well they do but more like an exception not a common thing)
