Munich - Anyone looking for fluid 3D gaming action or smooth video editing will need a powerful graphics card for their computer. When researching cards, potential buyers are typically faced with a range of manufacturer claims.

"That's the heart of a graphics card," explains Christian Wefers from hardware maker Asus. Far and away the most common chips found on graphics cards come from competitors Nvidia and ATI.
