I used to refurbish mac minis, and iMacs from near dead boards to working units. However, if the issue is upgrading the AMD dedicated graphics, and you wanted something newer - could a new logic board from a similar iMac of a newer setup be used to replace the current one, allowing for a better dedicated graphics option? A new logic board added to the price is a lot, I get that - but it's certainly cheaper than an new unit, and if the design doesn't change too much, and the power requirements are within a safe range I imagine it could work. This is just my two cents, and I realize it'd be almost easier to buy a new machine. How do you think, techinfernos, will it work? Did i miss something?) Here are the links to the macrumors forums.įrequently Asked Questions About NVIDIA PC (non-EFI) Graphics Cards - MacRumors ForumsĢ011 iMac Graphics Card Upgrade - MacRumors Forums The only problem is the 'EFI|' thing, so i will not have a boot screen any more. With the latest drivers from 10.8 - 10.9 it is possible to launch brand-new out-of-the-box mobile Nvidia. But after reading some threads on macrumors i understood that it is not true. The lack of RAM, very-very-very-very slow HDD (which is painfully dying) and of course 6970m 1gb which is a good, but not a high-end GPU for the end of 2013.įirstly, i thought about building eGPU because I read somewhere that upgrading imacs GPU is possible only with a higher model from the same series (e.g i have 6970m 1 gb and it is possible to upgrade it ONLY with a 6970m 2gb). So a month ago i understood that my 27' mid 2011 imac is not a beast-machine any more. If it is not - please remove/delete my thread. I'm not sure if it is right forum to post this thread.
