Over the several months, GPU prices, especially NVIDIA and AMD's latest generation graphics cards, have normalized in price, allowing more accessibility for new and current users to purchase the graphics card they need affordably. However, the market is gradually filling up with used GPUs from users and the crypto mining community's fair share of used GPUs in mining rigs. This overabundance of options in the used and retail marketplaces creates difficulty for consumers looking for an affordable option in used technology, unsure of the lifespan of the used GPUs.

Tom's Hardware has closely followed the price decline over the last several months and noticed that last month, prices dramatically fell for AMD & NVIDIA GPUs in the used marketplace, from sites like eBay. Last month, the used market witnessed a fourteen percent decline, with seventeen percent falling on the latest generation graphics cards, like NVIDIA's RTX 30 series and AMD's RX 6000 series. The retail markets have seen a less dramatic decline, only a three percent drop from the previous month.
