The highest result on the SPEC website for SPECint_base2000 I could find is 3108 with full optimization (-fast +FDO, etc.). 3.0 GHz Harpertown is almost surely faster than that "Precision Workstation 390 (Intel Core 2 Extreme processor X6800, 2.93 GHz)" that achieved the 3108, but not by a factor greater than 3. How did you come up with the 11751 score? If you were running SPECint_rate_base2000 at 8 cores, at full optimization, the score would likely be in the 200-300 range.
