As far as i know, overclocking is not about raw performance, but performance improvement over stock speed, except for World Record is different. Overclock Athlon 5350 to 4ghz maybe is harder than do 6700K to 6.5ghz. Thats why HWBot give Hardware Point (pure point for overclocking) and Global Point (for fastest overclocked system). So to make 3D popular you need to accommodate what people need, cheap oc. With cheap oc people will submit more and make your 3D point will naturally get higher point, even more than XTU if submission become more popular.
