slow internet loading, slow youtube response: Dell 5558

Hello, I have a Dell 5558 Inspiron.  the internet is very slow to load.  My wife has a macbook pro that runs circles around my PC for web browsing.  I have tried various tricks to minimize startup functions and background apps.  is this a hardware issue that can be upgraded?  would upgrading the GPU, upgrading to SSD, or adding more RAM help?
