Software packages: Avid, Premiere Pro, After Effects, Autodesk Entertainment Suite (Maya), Da Vinci Resolve

Blackmagic specifically recommends the GTX cards for CUDA processing over any quadro or tesla - I posted the doc above which says they prefer GTX. They just changed their recommendations to the 680 over the 580. The only reason I am purchasing a second video card is to use the GPU compute in Da Vinci Resolve. Quadro is for the Adobe CS and Autodesk.

Applications include editing and coloring regular HD footage as well as RED 2K and 4K which is why I am looking into the xeons as opposed to an OC'd i7.
