For editing, I've got a Mac Pro 2.26 8 Core, it's mostly stock right now, running 10.9/8.1. I need to get some more memory for it as well as a better gpu and then a 3D display. The Sapphire 7950 supports 3D and 4k so I think I might go with that one. I did get a Blu ray burner for it and installed but not much else other than a couple of HDD drives for it. Not doing any editing right now except some old mini DV tapes that I'm trying to get finished up that I found. That's running on an older G5 Mac sitting right next to my Mac Pro with Final Cut Pro. Talk about slow, try editing on that machine for awhile. I think it's ten years old now. I've got a Mac Book Pro, for web and stuff, a couple of mac mini's for each TV room for running Plex. An 8 Core Xserve to host everything, still trying to get enough HDD's to keep up with media I keep adding but it's a loosing battle. I need to start my next array of 24TB soon.
