Compare the exact version
Graphics card names can hide important differences. Confirm the desktop model, VRAM capacity and board manufacturer. Some products share a similar name while using different memory configurations or power limits. Laptop GPUs and desktop cards are not interchangeable, and an external enclosure listing may not include the GPU itself.
Measure the space in your case and check slot thickness, card length and power connectors. Confirm that the power supply is a reputable model with enough capacity. A low-priced card that requires a new case or PSU may not be the cheapest upgrade.
Evidence of a healthy card
Ask for a recent benchmark or demanding game test. Useful evidence shows the recognized model, stable performance and temperatures under load. Visual artifacts, driver crashes, rapidly changing fan speeds or unusual mechanical noise can indicate a problem. Clear photos should show the connectors, cooler and rear PCB area where visible.
A seller may have replaced thermal paste or pads. That is not automatically negative, but ask why the card was opened and whether the work improved temperatures. Repairs, modified firmware and missing screws should be disclosed.
Marketplace comparison
Regional platforms shape the European market. Kleinanzeigen is important for German local deals, Leboncoin for France and Wallapop for Spain. Vinted can contain components across supported regions, while Yaga and Osta can provide Baltic listings. PCPartDeals helps organize supported external offers without becoming the seller.
Check shipping and buyer protection on the source platform. For expensive cards, a small saving is rarely worth an unprotected payment method or a seller who refuses current testing evidence.
Choose by performance, not prestige
Compare the card with newer hardware that offers similar performance. Newer cards may include improved efficiency, video encoding or upscaling support, while an older high-end model may provide more raw performance but require more power. Use benchmarks for your resolution and games rather than relying on launch-tier labels.

Frequently asked questions
What should a used GPU test show?
It should show stable load performance, reasonable temperatures, working fans and no artifacts or crashes.
Does mining make a card unsafe?
Mining history alone does not prove damage. Current condition, cooling, fan wear and stability are more useful evidence.
