While video editing is a demanding workload that will benefit from more powerful GPUs, like the 80- or 90-series cards from NVIDIA or comparable AMD offerings, buying mid-range cards will be sufficient for most users. Even when editing 4K videos, a card like the RTX 3060 Ti can power your workload. The performance benefit that you'll gain by moving to a card like RTX 3090 or RTX 4080 will not justify the associated price increase. It's worth noting that NVIDIA GPUs have traditionally offered better support for video editing, 3D modeling, and rendering software than AMD's cards.
