Hello everyone, I'm new to the MAC world, I had the opportunity to purchase an iMAC 12.1 2011 a1311, I already exchanged the HDD for an SSD and I have 16GB of RAM. However, I would like to know what else I can change, I've already been through the forum, and I saw that I can put an i7 or a xeon, which I prefer the xeon, and in your opinion, which processor model and which video card can I use ?
