Sell your GPU
GeForce is NVIDIA's consumer GPU family, not a brand. Pick the series, the NVIDIA chip, then who built the card (ASUS, MSI, PNY, ZOTAC, Founders Edition, …). Specs come from nvidia.com. A sticker serial is looked up here for stolen/duplicate cards, not for VRAM.
Selling more than one GPU? Download the Excel-compatible inventory template and enter one physical GPU per row. Then upload the completed CSV in the bulk inventory workspace.
