Several of the linuxcnc kernels ran as daily drivers over the years since I built it in 2006. It was stuck in the 100 microsecond region. Original phenom, only aavailable for a month or so when I bought it, ordered slower 2.1 GHz version and never really pushed as it was a room heater anyway. This 6 core i5 runs 30C cooler than the phenom, and its doing it at 3.7GHz.
By '12 or '14, the phenoms had been optimized enough there likely could be considered a new family, die shrinks etc had pulled the fastest ones down to 95 watts. I inquired at Asus in about that time frame and was told the later ones wouldn't run on that nearly $300 board. Then that board burned up starting at one of the usb headers about 3 weeks back so I had to rebuild it. So this time I spent more on the cpu and less on the board.
