Hi all, asking on behalf of someone else. Specs: 20 inch iMac Early 2009 OS X Yosemite Processor: 2.66GHz Intel Core 2 Duo RAM: 2GB 1067 MHz DDR3 Graphics: NVIDIA GeForce 9400 256MB Storage: 320GB SATA HDD They have owned the computer from new but for the past couple of years it has been painfully slow, I couldn't use it myself. I have kept recommending them to upgrade the machine like I did with my mid-2010 MBP, especially as theirs isn't supported for Sierra. Nevertheless, they would prefer to upgrade parts than forking out for a new machine, but if a new machine is not much more than upgrading the parts then they will consider it. What's everyone's recommendations, especially on which RAM and SSD? They mainly use the computer for business work, minimum amount of storage required is 512GB I would say. How much do you think they could sell it for? It's like new with not a scratch on it. They are more likely to buy a new one then. Thanks. Edit: I am going to keep an eye out for Black Friday deals on iMacs.
