>Gaming computers with big GPUs are common.

Is there a good way to quantify this?

My best guess would be the size of the GPU market, before the AI crush.

I don't track that market (not a gamer), but it seemed substantial enough that I was aware of it. I do travel in geeky circles though.

Also, plasma TVs were big for a decade or so, and they run hotter than the CRTs that preceded them, or the LCDs/etc of today.
