Some healthy advice;
I was suckered into believing other peoples claims about what I "should" be getting. There are maybe 2 people I've come across that claim numbers like Dave. Maybe it's because they have Intel, or a faster chipset, or they turned the LOD bias all the way up, or overclocked, or etc... In the end, all the tweaking (BIOS, registry, Driver sets, Quake 3 Dll's/ bat files, windows reinstall's, driver cleanings etc) were all a waste of time with very little or no improvement.
