I don't know much about computers and I didn't want to mess anything up so I just told Puget systems to build me the fastest possible computer for video editing that they could for under $5,000. The computer is an absolute beast and can edit anything you throw at it. It's also great for gaming.

I used to work as an editor, but now I work primarily as just a cinematographer so I don't have a need for such a high performance machine anymore.
Here are the specs:

System Core
Motherboard: Gigabyte B550 Vision D
CPU: AMD Ryzen 9 3950X 3.5GHz Sixteen Core 105W
Ram: 4x Kingston DDR4-3200 32GB(128 GB Total)
Video Card: EVGA GeForce RTX 3080 XC3 ULTRA 10GB Open Air
Sound Card: Onboard Sound
Networking: Integrated Ethernet, WiFi, and Bluetooth

Storage
Hard Drive: Samsung 980 Pro 500GB Gen4 M.2 SSD and Western Digital Red 4TB SATA3

Chassis and Cooling
Case: Fractal Design Define 7
Power Supply: Super Flower LEADEX Platinum 850W
CPU Cooling: Noctua NH-U12AP
Additional Cooling: Arctic Cooling MX-2 Thermal Compound Case Fans Upgrade Kit (PWM Ramping)
Total Cost when I bought it in 2021: $4,495.26
