Graphic Cards are manufactured worldwide by Nvidia and AMD/ATI.But while choosing a graphic card for a desired price range which manufacturer card is best either Nvidia's or AMD/ATI RAdeon.I know that this is a big question to anyone and most of them would say that it depends on your price range and the purpose of using the card either for gaming or for using graphic intensive applications like Photoshop,3D rendering...etc.I came to know that Nvidia uses CUDA technology and not by AMD.Now i want to know that for gaming which card is best to choose and why? Does CUDA technology play a major role in gaming?
