Though I would love to get a iMac 5K I just hate to lose my investment in my current video/photo editing build plus I feel that my current setup configuration could rival the 5K and more. My only dilemma is that while my trusty and an absolute workhorse Nvidia Quadro 4000 can handle most of the editing for 4K it lag on it ability to perform several multitask process. So I need to upgrade some component. First the brain of the upgrade. PS: Once installed I will put my Quadro 4000 up on the Classified Forum if anyone is interested. This is an HP branded version which I found out was one of the most desired branded OEM. Don't know why and how but seasoned video editing folks seem to want HP more than the PNY or the DELL version.
