It is never a good idea to restrict Graphics Cards to playing video games. As a graphics generating machine, a Graphics Card helps you in so many ways than just in video games. Yeah sure a Graphics Card offers a smooth gaming experience with crystal clear graphics, but that's not what this thing is only built for. Graphics Cards offer us much more than allowing us to play graphics-intensive video games. From rending 3D images to playing high-definition videos, you need a Graphics Card as long as your PC is required to perform graphics-demanding tasks. If that's not the case, you are good to go without a Graphics Card.
