Money in the stock market (or crypto market but similar) is probably the only way to justify tens of thousands of dollars worth of GPUs that become obsolete quickly.

The other thing I can think of is Reseach scientists who use it for research. But funded research scientists that I know generally don't get hardware to take home. They usually either get tons of cloud credits or time on a supercomputer to do their stuff.

I sold a 4yo gpu for more than I bought it for not long ago.

It's the only thing in a pc that doesn't depreciate much these days, besides maybe the case.

Ah okay missed it. So not QF. I was hoping someone does QF at home :P

If my hardware can do it, point me to how I can do it! I'll give it a try and let you know how you changed my life. ;)
