the banik: To boards reviews...Why not? 99.9% users dont overclocking. Only the buy some components and put it in. Yes, this is reality. If one board will have diferent turbo at default BIOS setings, why not? It is added value of product. This added value in diferent turbo can have a bit negative side in power consumption. Of course, but good reviewer in review must this all aspect explain. This is my assumption.
