Ah yes, the much debated “PEG” feature on Asus motherboards.  PEG stands for PCI Express Graphics and the Asus manual states that it “enhances your PCI Express graphics card performance.”  It does this by overclocking the PCIe bus when it finds the GPU being used.  This does give you some noticeable performance increases, but also increases your chances of having an unstable system.  In one case, our X800 XT reference card refused to run a single 3DMark test without this option set to Disabled.
