Decision rule
Start with memory and workload fit
Use 16GB as the practical entry lane, 24GB when larger models matter, and 32GB+ when the buyer wants the most local LLM headroom from a consumer GPU.
Ollama GPU path
GPU shopping lanes for Ollama and local LLMs
Use this guide when the main job is running local chat, coding assistants, agents, or small lab services through Ollama. It keeps the Amazon clicks focused on capacity and system fit.

VRAM pressure
Why this workload gets expensive
Local LLMs can become VRAM-limited through model size, quantization choice, context length, and how many tools or sessions run at once.
Avoid this mistake
Do not buy on model name alone
Avoid buying for gaming-tier naming alone. A lower-tier card with more memory may be more useful for the intended local LLM workload.

Before checkout
- Start with target model size and context length, then pick a memory lane.
- Check PSU and case clearance before ordering a flagship card.
- Plan storage for local model files.
- Verify current seller and return terms on Amazon before checkout.

Parts around the GPU
2TB NVMe SSDs for model storage
Local model files, datasets, logs, and app caches can make storage a real part of the build.
ATX 3.1 power supplies
High-end LLM GPUs can require a modern PSU and a clean cable plan.
