Hi, So my Father is finally getting around to buying his first 27" iMac! He has a budget of £1720, including student discount of 15% as he is currently doing another degree. So looking up the available options, he will go for the 3.9GHz i7 for definite, but has a choice between upgrading the RAM to 16GB or the GPU to a 2GB 680MX. He does occasional photo editing and video editing, along with RTS games. While I'm aware that he may not need these specs, the insurance payout from his old computer provides that amount of money to spend on a new one. The RAM is user upgradable I believe, and it would be cheaper to upgrade it later on, if required. So what are your opinions on what to upgrade, the RAM to 16GB or to the 2GB 680MX? Cheers!
