Dell Inspiron 15 5558 CPU upgrade

I have a Dell Inspiron 15 5558 with an Intel i3-4030U and I want to upgrade to one with a higher processing power preferably one with around 2.5 GHz. Any recommendations?

RE: Dell Inspiron 15 5558 CPU upgrade

The CPU can't be replaced without also replacing the system board - and may require a higher-power AC adapter as well, so this may wind up a $400+ cost with labor.  It will also void your warranty, if that's an issue.

The board alone is about $250 -- add $50 or so if you need a higher capacity power supply, and another $30  for  a heatsink assembly if you're going from integrated to discrete video - plus the labor charge.
