Athlon II X4 610e & Phenom II X4 910e: 45W & 65W Quad Cores
 

The Athlon II X4 610e and Phenom II X4 910e are quad core processors from AMD with very low thermal design power of 45W and 65W, respectively. Are they as energy efficient as they claim and are the higher price tags justified? http://www.silentpcreview.com/cpu-2010-06
