Check the exact graphics-card variant
A GPU model or chip name is not a complete retail card identity. Memory capacity, board dimensions, slot thickness, connector requirements and cooling can vary between partner cards.
Before choosing parts
- Use the exact manufacturer card code before comparing dimensions or power connectors.
- Check installed GPU clearance with front fans and radiators in place.
- Treat VRAM capacity as a resource, not a performance ranking.
