Thank You, helps a lot. I am definitely keeping the DVD Drive though, use that a lot.

The CPU is soldered to the system board, so an upgrade means replacing the entire system board.  The cost for this will be upward of $300, plus any other hardware required (if you've now Intel video, and want AMD, you'll need to add a new heatsink and a new power adapter to the total, which will likely push the cost upward of $400.

Unless you're absolutely certain the CPU is running flat-out and an i7 would help, that's a steep cost for a system that's as old as this one.

If you're running a spinning hard drive, replacing that with a solid state drive will do far more for performance than replacing the system board will.

Thank you! I was afraid that's what it would be. That's disappointing, this is my first laptop. I normally do desktops (easier to upgrade). I am running a rotating hard drive. What SSD's could I put into this? Could I just replace the SSD and no other component?

You'll need a standard 2.5" SATA SSD.  There's only one internal 2.5" bay, so the hard drive will be replaced.

It may be possible to move the hard drive to a caddy and replace the optical drive, assuming you can find a third-party caddy and don't need the DVD drive.
