Wow, that took some time: I was mistaken at the time and thought I could build a dual CPU i7 system, however, multi cpu motherboards seem only to be available for xenon CPUs. I also use PowerDirector and GPU doesn't add much, have used in 6 core AMD and i7 IvyBridge 4 core with hyperthreading so it is 8 cores and the build below. The number of cores and CPU speed is so much more that the GPU doesn't hardly make a difference. The video editing build below powers through rendering, the only issue I have had is if I go out to color director and add correction, any machine I have tried bogs down. Don't know what's with that.
Also, 32GB of RAM didn't make much difference either vs 8 or 16
