Hello everyone

Im trying to replace some components on my pc

I edit video in vegas pro 16 and I want to improve the rendering and preview performance

I need a new cpu: I'm going to change my inTel i7 5820k for an AMD, which do you recommend since my rendering is in AVC format for bluray, I have a ryzen in mind but I don't know which one is right for my needs, which one do you recommend?

I need a new motherboard: I will replace my Asrock x99 extreme-4, I plan to grab the ASRock X570 Taichi AM4 ATX, Do you think it is right for my needs? Which do you recommend?

I need gpu: I will replace my 970 with something better since I struggle a lot in the preview of my project, i have to see it in the lowest quality to see a little more fluid my edition, what video card do you recommend for my needs?

I need a fast writing hard drive to help render, some m.2, which one do u recommend?

I have an EVGA 650 80 Plus power supply
I have 32gb of ram, Crucial Ballistix Sport LT 3000 MHz DDR4
I have liquid cooling, corsair I don't remember the model

Thank you very much for your help in advance, this is my first post and I hope I explained clearly
