Graphics cards depreciate differently than almost any other PC component. A CPU from three generations ago can still hold real value if it's still sold new. A GPU loses value the moment a new architecture ships — not because the old card got worse, but because the market's reference point shifted overnight. Understanding that shift is most of what you need to buy (or sell) used GPUs well.
The three things that set used GPU price
1. Where it sits relative to the current generation
A used card's price tracks its distance from whatever NVIDIA or AMD currently sells as their mid-range option, not its original launch price. A three-generation-old flagship and a one-generation-old mid-range card can end up priced within $20 of each other on the used market, even though they launched at wildly different price points, because they land in a similar place on today's performance curve.
2. VRAM, more than almost anything else
Compute performance ages reasonably gracefully. VRAM capacity does not — it's a hard ceiling. A card with 8GB of VRAM hits texture and resolution walls in current titles regardless of how fast its core is, and buyers who've been burned by this once tend to filter listings by VRAM first. 12GB and above tends to hold value noticeably better than 8GB cards from the same era, even when the 8GB version was originally the faster card on paper.
3. Mining history and thermal wear
Cards that ran 24/7 at sustained load (mining, render farms) aren't necessarily worse than ones used for gaming — but the market treats them as worse, which is what actually matters for resale. Listings that disclose mining use, or that come without original packaging and a recent boost-clock benchmark screenshot, sell for a discount even when the card tests fine. If you're buying to flip, factor in that you'll likely face the same discount when you resell, unless you can verify and document the card's condition yourself.
Rule of thumb for flippers: the safest margin isn't the biggest spread between new and used — it's the spread on a card whose used price has been stable for several weeks, not one that just dropped because a new generation was announced and the old generation's value is about to keep falling.
Reading a margin correctly
ChipFlip's margin number is the gap between the current new retail price and the median of recent actual eBay sold listings — not the asking price, which is almost always inflated relative to what cards actually sell for. A wide margin on a card with very few recent sold listings is a weaker signal than a smaller margin on a card selling consistently every week. Demand and margin both matter; one without the other is a flip that's harder to execute than the spreadsheet suggests.
