If you had a bunch of GPUs lying around, what would you actually build with them? (Running LLMs is off the table) [D]

Be honest if someone dropped a stack of high-end GPUs on your desk tomorrow, what would you actually do with them? And before the usual answers roll in: running local LLMs is banned for this thread. It’s been done to death and feels pretty pointless at this point. So… what else? Some niche scientific/simulation workload? Weird generative stuff that isn’t text? Distributed something-or-other? Rendering / media pipeline? Homelab experiments that actually need the horsepower? Completely unhinged personal projects? Drop your ideas. The more specific (and slightly unhinged), the better.
