Q: 8. Will this 64Gb RAM upgrade speed up a 2013 Mac Pro (currently with 32Gb RAM) running heavy video / 4K content and applications?

A: That depends. Are you running out of memory? If you still have 50% of memory available while you are running the app then you probably won't notice a difference. It might be possible you need a processor upgrade instead. Find out why it is running slow first, then upgrade the correct part. But, yes this will give you 32GB more RAM if you install the upgrade, and theoretically improve performance.
