Here is my dilemma. Our church has dove into the world of 4k video editing and as the primary video editor, I'm a little worried my iMac isn't going to be able to keep up (late 2013, 3.2 GHZ, 24 GB, 240 external SSD boot). I know the new iMacs are coming out probably in the 1Q of 2017, but I saw this on Adorama. Late 2015, 3.3 GHZ, 32 GB ram, 256 SSD internal for only $1899. More than $600 off. http://www.adorama.com/acmf885lla18.html I want to pull the trigger, but don't know if I'm really getting that big of a processor upgrade and if an i5 will be okay for 4k.
