Upgrading Computer

What exactly is your question here? You've just stated some very basic info.

Also, what you're calling an 'upgrade' is more of just a whole new computer build. Rather than thinking of it as an upgrade, just make it a new computer build while re-using parts from your old computer (hard drive, disk drive, what ever else will work).

Without knowing the full specs of your computer, we cant give you any advice on what you can re-use or will need to upgrade.
