Buyer rule
Start with the engineering workflow
Start with software version, CUDA support, compute capability, driver path, VRAM target, RAM target, operating system, storage, and backup power.

CUDA MATLAB GPU compute workstation
GPU compute workstations should be bought around software support, compute capability, driver path, VRAM, system RAM, storage, and repeatable setup. A card that is fast for games is not automatically the right compute card.

Risk
The common mistake is choosing a GPU by model tier alone without checking CUDA support, compute capability, driver compatibility, VRAM fit, cooling, or Linux support.
Amazon engineering lanes
Use these lanes after the software, solver, GPU support, memory, storage, network, and power path is specific. Amazon has the live listing details, seller terms, shipping, returns, and exact product specifications.
System lane for CUDA development, MATLAB GPU arrays, engineering scripts, and local experiments.
Capacity lane for local compute jobs, larger arrays, models, and engineering experiments.
Headroom lane for buyers who expect VRAM limits to decide what can run locally.
System lane for buyers who want a Linux-friendly CUDA development and compute setup.
Storage lane for datasets, scratch folders, checkpoints, logs, and local results.
Memory lane for larger host-side arrays, preprocessing, local datasets, and multitasking.
