People with "non-enthusaist hardware": how do you use it?

I don't want to be super gatekeepy about this, but let's loosely define "non-enthusaist" as "a single consumer grade graphics card on a system that's not primarily dedicated to inferencing."

While it's fun to see what people can do with more dedicated build$, I'm never going to put hands on hardware at that price point. I'm interested to see what people accomplish with more humble means.

Is there a particular agentic task that you find super useful or are proud of?
