Your system is seriously underpowered for what you are asking of it with a 10 camera angle multicam.
- Not enough cores.
- Not enough memory.
- Not enough disks.
- GPU is irelevant here.
Thanks for answering, I did not know I needed both processor for videos, thought was GPU
What gpu do you recommend for premiere and after? Quadro or GTX?
Already answered in the link I gave.
GPU acceleration is not used at all for playback. It's only used to render certain effects, blending modes, frame rate and resolution mismatches.
Multicam with raw clips is all CPU.
