Quick Answer

For 3D modelling and rendering, 3D modelling and rendering (Blender, Cinema 4D, Fusion 360) wants high core counts for CPU rendering and a GPU with plenty of VRAM for viewport and GPU rendering. A Ryzen 7 7700 (8 cores, around R6,000) plus an RTX 4060 8GB is a workable R20,000-class workstation. Everything below is currently stocked at Evetech with courier delivery to Knysna.

What actually matters for 3D modelling and rendering

Stretch to an RTX 4070 12GB where the budget allows — VRAM is the limiter in GPU rendering, and 32GB DDR5 plus a 1TB NVMe keep scenes and caches responsive. Render performance is measured in samples and minutes, not fps: an RTX 4060 in Blender's Cycles (OptiX) renders a typical scene several times faster than CPU-only, and 32GB RAM prevents out-of-memory crashes on dense meshes.

How to budget the build

Spend the most on the part this workload leans on, then round out memory, storage and a quiet power supply rather than chasing a single headline component. A 1TB NVMe SSD (around R900–R1,200) and 32GB DDR5 are the upgrades that pay off across almost every 3D modelling and rendering workflow.

Buying and delivery in Knysna

Garden Route buyers in Knysna get the full Evetech catalogue delivered by courier. Fibre from Vumatel and Openserve reaches most suburbs, with 50–200 Mbps lines common for online play, downloads and updates. Every component carries the standard local warranty, so a fault in Knysna is handled the same way as in George/Cape Town.

FAQ

CPU or GPU rendering for Blender in SA?

GPU rendering with an RTX card and OptiX is far faster for most scenes. An RTX 4060 8GB is the entry point; an RTX 4070 12GB handles bigger scenes thanks to more VRAM.

How much VRAM do I need for 3D rendering?

8GB is the practical minimum and handles most hobby and freelance work; 12GB+ (RTX 4070 and up) is better for dense scenes and 4K textures, since VRAM is the hard limit.

How much RAM for Blender and CAD?

32GB DDR5 is the comfortable target for modelling and rendering; complex scenes and simulation can push past 16GB quickly. Pair it with a fast 1TB NVMe for cache and asset libraries.

Match the part the workload leans on first, then confirm stock and warranty with Evetech before ordering to Knysna.
