CTurbo :
It would be cheap and easy to find a used LGA1156 i5 or i7. Maybe you can do both.
I already tried it, the only LGA1156 I could find in my country was the i7 for ~82$ I mean sure it's still a lot cheaper than buying a new mobo + processor but it's still an old and weak processor and for the same money I could buy a brand new x4 860k or Fx 4320
