Hi, I am new to these forums. I want to build a new system. I am looking at AMD because of price and overclocking. But I am honestly a little concerned about the numering system of AMD. Can a AMD Athlon Thunderbird 1.5 GHz be overclocked to 2.3 GHz 850.0 MHZ? I need advice on the Best inexpensive Motherboard & CPU to overclock that supports a ATX case?
