Bits of dmesg:

atapci1: <nVidia AHCI controller> port 0xd480-0xd487,0xd400-0xd403,0xd080-0xd087,0xd000-0xd003,0xcc00-0xcc0f mem 0xfae7a000-0xfae7bfff irq 22 at device 9.0 on pci0
atapci1: [ITHREAD]
atapci1: AHCI v1.20 controller with 6 3Gbps ports, PM supported
ata2: <ATA channel 0> on atapci1
ata2: [ITHREAD]
ad4: 1430799MB <Seagate ST31500341AS CC1H> at ata2-master SATA300

Also kenv:
smbios.planar.product="M4N78 PRO"

This system has a newer CPU than the one you were timing:

CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 5200+ (2700.02-MHz K8-class CPU)

Are you seeing a lot of system and/or interrupt time when you do your
benchmarks?
