Thank you, a very useful post for me. I think the flexibility of a PC will in the long run serve me better. I just guess I will need to be patient on the GPU front. However as I do little 4k work and special effects, I am wondering should I build my PC and install a lesser GPU until a GTX3070 comes along. The trouble is I am not sure what to get that would serve me well in the meantime. Any ideas?So I actually own an M1 Mac Mini and am using with with Davinci Studio. It is as fast as my 16" MBP, but not as fast as my PC with the GTX2080ti. With that said, I still do 90% of my editing on the MBP or M1 Mac Mini. It isn't drastically slower.
FCP is one of the apps that is optimized for the M1 chip.
If you don't need to render 4k video, I'd say go for the best deal. If you are working in 4k or doing a lot of effects rendering, then the PC is a good way to go.
