I am buying one of these off newegg later today. It is kind of funny because I do not know which one to get! I heard that the new KAB7E 3700+'s are good but also I heard the Opteron 148's on newegg are CABYE 0542, the best stepping. And also, when is the latest I can order with Next Day Fedex and still have it ship out today? Thanks dudes!
