I bought a Tesla K80 for ~$200 off eBay, and now it's going for less than $150, and you can essentially get the same but just 1 GPU for $100. It has 12 GB of VRAM, and works great for "medium-duty" machine learning and AIs like Stable Diffusion. It does run hot (150W per GPU), and I've had to make a [custom solution to cool it](https://github.com/askiiart/k80-linux-cooling https://github.com/askiiart/k80-linux-cooling), but it works great considering the price. By the way, you can essentially never have an application use the 2 GPUs in parallel in any useful way; I'd suggest just getting a K20X instead.
