Amd Processor (Athlon II X4 or Phenom II X2)

Looking for an AMD CPU ,preferably an Athlon II X4 or Phenom II X2. Warranty is not an issue but should be perfectly functional with the cooler present. Given that current Athlon II X4/Phenom II X2 cost about 4.5k - 5k in market, the price shouldn't be more than 3k. It should be compatible with AM2+ socket (all of them generally are compatible), for the Asus M3N78-EM motherboard !

P.S : If you have good price on a Phenom II X4, I may buy it !
