I just installed it and it's reading 64

on one core @ 52% (F@H running) and 42 on the other @ 12%. EasyTune5 HW monitor is showing CPU @ 48. Checking the heatsink, it's not exactly cool to the touch but it's not necessarily hot either. Air from the cpu fan is cool. I'd think at 64, I'd see some degradation in performance or something odd at least. I don't know which one to believe.
