In the early days of overclocking for me there was a site I went to more than any other, DFI-Street.com. It was all about those mythical motherboards made by a man by the name of Oskar Wu. Oskar Wu used to be the main man behind those legendary Abit boards (I used to have one of them with an AMD Barton overclocked to the moon) For those of you not in the know, DFI-Street dismantled after DFI got out of the high end consumer motherboard business. This happened to correlate with the removal of the performance crown from AMD, when Intel handily destroyed them with their Core series (which was just a crazy new PIII mobile, more on that at another time) During this age AMD was king, no one was using ATI, and the all important WD Raptor in a Raid0 config was faster than anything alive.
I would say I am remiss that what was going on at DFI-Street was never full replaced for me, and in its place a new breed of site stepped in to take the format of the forum away almost completely.
I leave you with a couple of screen shots from when I qualified the overclocks on my AM2 CPU back on the street, circa 2006.
