Our test system remains unchanged for our K8 setup. We used our trusty Athlon 64 X2 3800+ CPU. When doing overclocking tests we try to reduce the CPU speed down as close to stock speed as possible with lowering the multiplier, this lets us know if there are any benefits from the overclocking the bus speed to be gained.
We are comparing the ASUS Crosshair against the DFI NF590 SLI-M2R/G Lanparty at stock and overclocked speeds. ASUS was running at 2.16GHz (or 361MHz FSB x 6) and DFI was running 2.25GHz (or 375MHz FSB x 6) with DRAM running at 1:1 ratio. DFI has the pure clock speed advantage coming into the race but let's see what story the benchmarks paint for us.

SiSoft Sandra (System ANalyser, Diagnostic and Reporting Assistant) is a synthetic Windows benchmark that features different tests used to evaluate different PC subsystems.
At stock ASUS just pulls ahead because of its slightly higher bus speed it runs the CPU at when clocked at stock, when overclocked, ASUS pulls just ahead of the DFI board.
