Quick Answer

A 4K video-editing rig in Knysna needs an 8-core-plus CPU, 32-64 GB RAM, a high-VRAM NVENC GPU and fast NVMe scratch storage. A Ryzen 7 7700 (or Ryzen 9 7900X), an RTX 4070 12 GB, 64 GB DDR5 and a 1 TB NVMe plus a footage drive edit 4K DaVinci Resolve and Premiere timelines smoothly. Budget around R28,000-R35,000; 4K editing is substantially heavier than 1080p.

What 4K editing demands

4K timelines with effects and grades are RAM- and GPU-intensive:

  • CPU: Ryzen 7 7700 (R6,000) minimum, Ryzen 9 7900X (R8,500) for faster export
  • GPU: RTX 4070 12 GB (~R12,000) - VRAM and NVENC for smooth 4K
  • RAM: 64 GB DDR5 (~R4,000)
  • Storage: 1 TB NVMe OS + fast scratch NVMe + footage drive

A dedicated NVMe scratch disk keeps 4K playback fluid by absorbing the large cache writes.

Software, monitor and Garden Route delivery

DaVinci Resolve and Premiere Pro lean on the GPU and VRAM for 4K. A wide-gamut 1440p or 4K IPS monitor (~R7,000+) helps you grade accurately. Knysna is on the Garden Route, so Evetech deliveries take 3-4 business days; coastal humidity means keeping the PC ventilated. Power-test before signing.

FAQ

Why does 4K editing need so much more than 1080p?

4K has four times the pixels of 1080p, so playback, effects and export demand far more GPU power, VRAM and RAM. A 4K rig needs 64 GB RAM and a 12 GB+ GPU where 1080p is happy with 32 GB and 8 GB.

Can I edit 4K on an RTX 4060?

You can with proxies, but it struggles with effects and grading at full resolution. An RTX 4070 12 GB is the comfortable minimum for fluid 4K editing in DaVinci Resolve and Premiere.

Does Evetech deliver to Knysna?

Yes, Evetech ships to Knysna on the Garden Route in 3-4 business days. Power-test the PC before signing the courier waybill.

TIP

footage on a separate fast NVMe from the OS and use Resolve's proxy workflow - it removes the read write bottleneck that causes 4K playback to stutter during editing.
