I'm trying to upgrade the CPU/processor but I don't know where to buy
So apparently I can upgrade the CPU to 4.0GHz quad-core Intel Core i7 but I am new to all of this and have no idea where to buy it. Which one is compatible with my computer and from which reputable, trusted store?
iMac (Retina 5K, 27-inch, Late 2015)
Это хороший вопрос?
