Choose around the workload
Consider the games, resolution, rendering engine or compute framework you actually use. For local AI, account for model weights, quantization, context length, batch size and software overhead instead of selecting from an AI TOPS headline alone.
Check the offered board, not only the GPU name
Confirm the exact board manufacturer and model, case clearance, card thickness, cable bend clearance and power connectors. NVIDIA reference dimensions and PSU recommendations do not describe every partner design or complete PC.
Review deployment and software support
For hosted services or data-centre operation, review the applicable software licence and driver terms and consider enterprise alternatives. For workstation applications, verify the exact application and operating-system support.
