Search eBay for a graphics card and a lot of what comes back isn't a graphics card. Before a listing reaches gear.casa it goes through two steps: we throw out what isn't a working card for sale on its own, then we work out exactly which board it is.
What we filter out
These listings name a card in the title, so a plain search puts them right next to the real thing, often at a price that looks like a steal:
- Fans and shrouds. Replacement fans, cooler shrouds and housings sold "for RTX 3080".
- Bridges and brackets. SLI and NVLink bridges, support brackets, water blocks.
- Box only and photo only. An empty retail box, or a listing for a picture of a card.
- Laptops. A laptop with an RTX 4070 inside is not an RTX 4070 you can put in your PC.
- Whole PCs. Prebuilt gaming PCs and bundles that come with a card.
- Multi-card lots. Five cards for one price can't be compared with one card.
Cards sold for parts or not working are kept, but marked Broken and hidden unless you tick Broken under Condition.
Matched to the exact board
An "RTX 4070" isn't one product. ASUS, MSI, Gigabyte and a dozen others each make several versions, and a Dual, a TUF and a ROG Strix of the same chip sell at very different prices. So every listing is matched to one board: the brand, the model and the version.
The match uses the listing's title, the item details the seller filled in on eBay, and the photos. Only listings matched to one board make it into the table. When a listing could be one of several boards and nothing settles it, it stays out rather than us guessing.
Prices you can compare
Because every listing is tied to a board, the prices next to each other are for the same thing. That's what makes the price check and the price history work: a used card is only compared with other used listings of the same card.
The prices are asking prices, not sold prices. About explains what that means and how we make money.
