RTX 3090 Used Prices Hit $1,300–$1,500 on eBay Amid Local LLM Demand

Used RTX 3090s are selling for $1,300–$1,500 on eBay, near the $1,550 price of new units on Amazon, driven by demand for local LLM inference rigs. The 24GB VRAM capacity makes the 3090 one of the few consumer cards capable of running larger quantized models.
