Buyer rule
Compare the whole system
Start with VRAM and RAM, then check storage, thermals, PSU headroom, case airflow, and upgrade path.
Local AI prebuilts
Buy the whole local AI workstation around VRAM
A local AI workstation needs enough GPU memory, system RAM, storage, cooling, and screen space. Use these Amazon lanes to compare complete systems and the parts around them.

Risk
Avoid the specification mismatch
The common mistake is buying a gaming-first prebuilt that has the GPU name but not enough memory, storage, or cooling for local AI work.

Before checkout
- Check GPU VRAM before comparing processor names.
- Make sure system RAM and NVMe storage fit the intended workflow.
- Check cooling and case airflow for sustained GPU load.
- Confirm upgrade slots, warranty, seller, shipping, and return terms.
