There is no point in stating the obvious about which processor in this reference list is the fasted in Sysmark 2004, the interesting split is which platform the Intel Core 2 Duo E6750 was tested on handles best. Using the E6750 processor with a mid-level nVidia nForce 650i nets us results which are a hair less than those for the Intel P35 Express with DDR2. The P35 Express and DDR3 platform posts the slowest results (technically), but not by a very significant margin.
