Upgrading a graphics card is probably not a good idea for someone who is "an idiot when it comes to computers." For starters, a new graphics card may not even result in any performance increase if you PCIE bus or CPU can't keep up with it.

They are available just about everywhere and are relatively inexpensive. You may need several depending on how much you have to back up.
