For your CPU, I'm not 100 percent sure, but I don't think that the AMD Phenom II X6 1100T CPU has AES hardware instructions. Without hardware AES, CPU mining ANY cryptonote coin (like ETN) will be very inefficient. I don't know their current profitability, but check into mining Magi (XMG) or Zcoin (XZC) with your CPU. I don't think those algorithms use AES.
