I have a good configuration computer and Windows xp installed in it. I am able to play many games very smoothly. But some games needed graphic card without which it was not possible to play such games. Thus I needed to buy a graphic card so I planned to have pci express graphics card. I choose this because this card was very useful for gaming purpose. But I don’t know what the use of high memory graphic card is. Also I want to know some more advantages related to it.
