If I'm not mistaken a graphics card can also be referred to as a GPU right? My current graphics card/GPU starts with the word 'NVIDIA'. I'm thinking of getting a better graphics card/GPU. But the one I'm thinking of getting has a name that starts with 'AMD Radeon'. If your graphics card is a NVIDIA one ,then must your new graphics card also be a NVIDIA type? Sorry if I sound ignorant about PC stuff.
