If there is one element of the PC that has evolved a lot in recent years it is the graphics card, also called a video card. Indeed, barely ten years ago its role was limited to transmitting data to the screen for display through the VGA or S-VGA output. Today the graphics card, in addition to this essential function, also plays the role of coprocessor for 3D and greatly lightens the load on the central processor by taking care of the calculation of certain graphic effects and 3D calculations (textures, etc.).
Today, only applications including 3D (mainly games and some professional 3D applications) require powerful graphic cards with prices ranging from 30 to over 1000$. All the other applications such as office automation, internet surfing, video editing, photos do not require any additional 3D accelerating power from the processor
