I used DaVinci systems at various facilities in Dallas, TX from the Classic in1984 to 2K Plus in 2005. I went out on my own in '05 and built my successful grading business with Final Touch and Color (freelance on SCRATCH & Lustre). I've read BMD's Resolve config guide, Reduser and certain forums on Creative Cow.
I grade RED, Alexa and many HD formats for broadcast, digital projection, DVD/Blu-ray, Web, etc. No film outs or 3D.
I understand Resolve uses CUDA GPUs and 1-3 is ideal. Especially with noise reduction.
My question is; Do I really need a 12-Core MacPro, or is my 2010 8-Core 2.42 'Westmere' with BMD recommended RAM sufficient for what I do?
