Generally speaking, you can't modify laptops very much. You can swap out their hard drives, you can up their ram (maybe), but installing graphics cards usually isn't possible.

Looking at the summary at the top, however, I suspect this particular machine already has a graphics card. The "AMD Radeon R7" mentioned in the upper description is a graphics card.
