Hello, I’ve recently purchased an I Mac and while I love it, I would like to upgrade the RAM, Processor and, Graphics Card. I am already in the process of ordering more RAM (I’ll be upgrading from 8 to 32 gigs) but, as ive heard, the processor can be upgraded as well, but i’m not entirely sure if, first of all, that’s true, or what it would upgrade to. And lastly, I don’t know if the graphics card can be upgraded at all. any help would be appreciated.
