Winbench 99 V1.2	Source: e-Testinglabs.com

WinBench 99 is a subsystem-level benchmark that measures the performance of a PC's graphics, disk, and video subsystems in a Windows environment. WinBench 99's tests can run on Windows 95, Windows 98, Windows NT, Windows 2000, and Windows Me systems.

It's odd, I'm not really sure why the disk portion of the benchmarks are so low. Also, usually when overclocking the PCI's the disk performance suffers a bit. With the slight overclock, we see that the AGP appreciates it.

Here we see the might of the motherboard. The CPU scores are on par with what we expect but the memory bandwidth is very high!
