processor upgrade on my lenovo e51-80 intel pentium

Solution
This one comes with an i5 and is the same model number that you listed https://us.hardware.info/product/317579/lenovo-e51-80-80qb0006ge/specifications

EDIT: What specific processor do you currently have. If you are usure, dowload and run CPU-Z HERE

If you are running the socket that I believe you are, this CPU (i7-6600U) should fit but I can't comment on the cost-effectiveness of the upgrade
