PC for Video editing

Hello volks hope you are all well,

So I am an Videoeditor and want to upgerade my PC.

My specs so far:

NVIDIA GeForce GTX 1660 SUPER

AMD Ryzen 7 3700X 8-Core Processor

Micro-Star International Co., Ltd B450 TOMAHAWK MAX (MS-7C02) 1.0

G Skill Intl 16 GB DDR4 UDIMM Ram

Unfortunately I know not much about the new Gen. But so far I was thinking about an RTX 3090 and an AMD Ryzen 9 5950X Processor.

Also I don't know if they fit. But I'd be happy for some feedback and Ideas. :)

PS: 3k Budget so far.

Best regards,
