Well the "AMD Radeon 7950 HD" is the actual graphics chip as AMD does not make the entire graphics card only the graphics processor within the card. So the card it self will be made by a separate vendor such as XFX, Gigabyte, ASUS, Sapphire, EVGA etc...etc... You will have to research the difference between these vendors as some may offer factory overclocks or different cooling solutions or even better quality boards and electrical components over other vendors.
