The Sapphire board holds the slightest of advantages over the Abit in the Everest memory performance test, but is then convincingly bested by 7ns in the memory latency test by the Sapphire, when both are set to identical 5-5-5-15-2T memory timings at 1,066MHz DDR2.

And in the Sisoft Sandra memory tests, we again see the Abit board lead, with the slightest of margins in the unbuffered memory test. However the Abit drops a significant
22ns in the memory latency test to the Sapphire.
SATA Performance

We used a Western Digital RaptorX 150GB and HDTach 3.0.1.0, with the 8MB Zone Test to record the average read performance.

Both boards performed perfectly, achieving the maximum possible score of 82MB/s over SATA with the RaptorX hard drive. Neither board features eSATA or adapters explicitly, however the internal ports can be converted to eSATA because both support ACHI mode in the BIOS.
USB 2.0 Performance

We used a Western Digital RaptorX 150GB connected to a USB to SATA adapter and HDTach 3.0.1.0, with the 8MB Zone Test to record the average read performance.

USB performance is pretty abysmal for both boards, considering that on an Intel ICH with USB 2.0 you'll easily achieve 30-35MB/s USB transfer speeds. The Abit is slightly ahead, but in this instance both boards are victims of the poor AMD SB600 south bridge.
