Yeah, 3.2 GHZ is a bit low, and 30 % turbo seems a bit high to me. But we're comparing it with todays K10 which wasn't designed for six cores and turbo from the beginning, yet it still got it today.
BD's 32 nm and power saving features may be enough for that high turbo. On the other hand, Intel only goes 400 MHz turbo with their upcoming i7 2600.
