I found a Gigabyte RTX 3080 Gaming OC listed for $275 after negotiating down from $350, which is about the going price for this model locally. The seller doesn't have a complete computer, so they can't demonstrate that the card works. Professional testing would cost around $100 and would make the deal much less appealing. Would bringing my own computer to a library and checking whether the card displays an image be enough, or should I verify that it boots into BIOS or Windows and run additional checks? Is there a better way to protect myself from buying a faulty or counterfeit card?

Simply seeing the computer power on or the card’s lights turn on doesn’t prove much. The card should produce a display and let the system reach BIOS or Windows. If possible, check that the drivers load and that the card is recognized correctly.
If you’re already going to the trouble of testing it, don’t stop at the lights coming on. Let the system boot fully, verify the GPU model, and run something demanding for a few minutes. That won’t guarantee long-term reliability, but it can catch most dead-card, artifacting, and overheating problems.
I wouldn’t count on using a public computer for this. The staff may not allow hardware swaps, and those systems might not have the right power supply or drivers anyway. Bringing your own compatible PC is much more practical.
The safest option is to bring your complete setup, including a monitor, and test the card in your own system. Once you’re in Windows, use GPU-Z or Nvidia’s system tools to confirm it’s actually an RTX 3080, then run a short game or stress test while watching for crashes, artifacts, or overheating. At $275, it’s a good price, but only if it works.
That probably makes the most sense. I was hoping to avoid hauling my large case and monitor around, but carrying everything is still better than risking the full purchase price.
Exactly—public computers usually aren’t available for testing personal components, so arranging a proper test with your own hardware is the safer plan.
