Video Editing that will last and last

If you missed the full set of required built request questions, please copy them from here and answer them in an edit to your post:

• New build or upgrade?

New Build

• Existing parts/monitors to reuse? (List with models/links)

EVGA SuperNOVA 1200 P2 1200 W 80+ Platinum Certified Fully Modular ATX Power Supply

• PC purpose? (Gaming, editing, etc. List apps/games)

I am looking to build a PC for 8K/9K video editing that I can get at least 5 years out of. Additionally, the PC sits in a room in which I podcast and do voice-overs so silent and deadly is what I need.

• Purchase country? Near Micro Center? (If you're not in a country supported by PCPartPicker, please list some local vendors)

USA, will likely be ordering online for everything

• Monitors needed? (Number, size, resolution, refresh rate)

Already have a huge Dell

• Budget range? (Include tax considerations)

<$4000

• WiFi or wired connection?

wired LAN

• Size/noise constraints?

Full size tower is fine--as silent as possible

• Color/lighting preferences?

no lighting needed

• Any other specific needs?

Here is some additional helpful information about build/upgrade/parts list requests:

Here is what I am thinking so far, but I will happily defer to your expertise:

AMD Ryzen 9 9950X 4.3 GHz 16-Core Processor

be quiet! Dark Rock Pro 4 50.5 CFM CPU Cooler

MSI MEG X870E GODLIKE EATX AM5 Motherboard

Corsair Vengeance 128 GB (4 x 32 GB) DDR5-5600 CL40 Memory

be quiet! Dark Base 900 ATX Full Tower Case

Questions:

Is that MoBO worth the money or should I go with something less expensive like the MSI MPG

What graphics card? I don't think a 4090 will fit in the budget. Will a 4070 work out--which one is best?

Is the corsair ram the best DDR5 or do you have better recs?

I can't thank yo enough for your help!!!!!
