I was curious about that as well. He probably doesn't tell because there would be instant arguing. To be fair though, hardware development feels like it has slowed down while the parts are becoming more expensive.

I have a thing where I wait to upgrade my workstation until performance of newer hardware has 2x'ed on most workloads. I had to wait quite long this time. My trusty 1080 Ti was not 2x'ed until fairly recently, and that came at a hefty price and much increased power draw. It feels like a lot of low hanging fruits have already been picked.
