Quick Answer
A practical local LLM workstation should start with 32GB to 64GB RAM, a modern 8-core CPU, and an NVIDIA GPU with at least 12GB VRAM. For Rustenburg buyers, the sensible SA planning band is R28,000 to R45,000, with Ryzen 7 7700, Core i7 class CPUs, RTX 4070 SUPER, RTX 4060 Ti 16GB, 1TB to 2TB NVMe storage as the kind of shortlist that keeps the build specific without inventing live stock prices.
Core Spec To Prioritise
Build around 7B and quantised 13B models, coding assistants, embeddings, Docker, and small RAG tests. The target is a machine that stays responsive after week one, not a tower that wins one benchmark and then runs short of RAM, VRAM, or storage. Keep the PSU reliable, leave airflow space around the GPU, and choose a motherboard with enough M.2 and USB support for the way the PC will actually be used.
Budget Signals For SA Buyers
Use R28,000 to R45,000 as a cautious category band, then compare current Evetech bundles by CPU, GPU, RAM, SSD size, and warranty clarity. A cheaper build can make sense when it still keeps 32GB RAM and a 1TB NVMe SSD; a pricier build is easier to justify when it adds real VRAM, quieter cooling, or a stronger CPU tier.
Local Setup Checks In Rustenburg
In Rustenburg, delivery timing, packaging condition, and first-day testing matter as much as the spec sheet. Openserve or Vumatel fibre helps with model downloads, but local SSD space matters because one model folder can be 5GB to 40GB. Test the tower with the exact app or game that drove the purchase, then keep the component list and packaging until the system has passed a real workload session.
FAQ
How much VRAM is enough for local LLMs?
12GB is the realistic starting point for useful local testing. 16GB or 24GB is better for larger quantised models, but only worth it when LLM work is the main reason for the PC.
Should I buy more RAM or a faster CPU first?
Buy 64GB RAM before chasing a flagship CPU if you run models, IDEs, browsers, and databases together.
Can this rig still game after work?
Yes. RTX 4070 SUPER class hardware can target about 60 to 90 fps in heavier 1440p games with tuned settings.
