I have a GPU server (4 × RTX3090s) that I've been using for research and PoC in the past 2 years. Mostly running vLLM for Qwen, GPT-OSS, and Gemma. My workflow is testing code on it where I have sudo permission, then deploy code and model on my office's servers with professional cards.
GPU prices went up a lot this year. Used RTX3090 on Ebay is around $1100. Plus, as FP8 and FP4 become more popular while RTX3090 doesn't support them, I wonder if it's time to sell.
My optimistic plan is to sell all 4 of them and get ~$3500. Use cloud API for a while. Later, if i have extra fund, upgrade to RTX PRO 6000.
Any thoughts and comments are appreciated.
