Well "luckily" one of our critical servers died during a scheduled shutdown so I got to take v2.1 out for a spin to address this.
Two words: Holy &^%$%@!#$$!
I thought the jump from 1.0 to 2.0 was impressive, this is just as good. Power delivery is insane and smooth. It "felt" like I was getting a throttle cut in the mid-band before (never logged to confirm), but nothing now. It's just a demon.
