Hello all, I currently have a 3,1 Mac Pro that I purchased last year. It is the 8-core 2.8 GHz model with 16GB of RAM and a SSD and a GTX 960. I am a part-time casual video editor, and am starting to notice a small amount of slow down when the people I began editing for began using 4K video. The income earned to time spent ratio is not enough to justify building a full rig/hackinitosh to edit this video, as the mac pro usually does it without a hiccup. I was wondering if upgrading to a 4,1 would be a good (cost effective) decision and eventually upgrade to a 8 or 12 core cpu tray later on down the road. I also use my computer for school (an computer major) and emulation of different OS'es.
