As Bitcoin miners sell off their nearly-useless graphics-card stuffed mining PCs, where will those machines go? The miners are either going to be left with awesome videogaming rigs (Skyrim at 8000px on a wall-size HD TV, anyone?), or else the Poser/Daz 3D rendering market is about to see a flood of high-end graphics cards on eBay. Those running a GPU renderer, and in the market for a ninja graphics card or two, may want to keep an eye on eBay in the coming months.
