I am pulling the trigger on a new CPU, (because I am putting my 940 in my wifes suprise quad-core upgrade) and want to make sure this is the CPU I want. 4Ghz sounds fun. This is the 125W model, so I think it is the C3, but I do not see it anywhere in the description. Anyone know how to tell? http://www.newegg.com/Product/Product.aspx?Item=N82E16819103727 Thanks fellow TPUers.
