You can buy 2 of them from Central Computer any day of the week for $30K US, and that's not the lowest price I've heard lately.

So if you can spend $30K and immediately start mining $1500/month out of thin air, that's a pretty nice investment even if the electricity costs $200/month. Two years later the cards will have paid for themselves entirely and (I suspect) will still be pretty useful.

It does argue in favor of just paying OpenAI or Anthropic for tokens, though.
