I was for a while. Hosted a LOT of stuff on an i5-4690K overclocked to hell and back. It did its job great until I replaced it.
Now my servers don’t lag anymore.
EDIT: CPU usage was almost always at max. I was just redlining that thing for ~3 years. Cooling was a beefy Noctua air cooler so it stayed at ~60 C. An absolute power house.
I retired mine with a 12600K and I’m not sure what to do with it now.
