No, a graphics card does not store any permanent data like programs or games. The video memory (VRAM) on a graphics card is just like regular memory--it is volatile. This means that any game information stored in the graphics card memory is removed as soon as you close the program it is associated with or turn off your computer.
Most video games can run on the graphics cards provided on the computer. If a different graphics card is needed it can be easily purchased online or at a local technology chain store.
a graphics processing unit or graphics card is the "device" that works with your CPU to display 3D and 2D graphics for various games and programs.
There are a wide variety of different places where one can purchase a GTX690 Graphics card. The best place to find the graphics card is at a local electronics store such as Best Buy.
The graphic settings on games such as WOW and Crisis 2 do depend more on your graphics card rather than your processor speed :)
For serious PC gaming, a graphics card is a necessity. That being said, there are plenty of games which can be played with only a decent CPU. A list of older games such as Half Life and StarCraft should run well on a modern machine without a graphics card.
The Radeon graphics cards are some of the best available. The card will improve the apperance of your games.
You have to buy an external Graphics Card one from a computer hardware store
It is a computer monitor/tv but on a computer/games console, the graphics are generated by a graphics card.
For regular applications you won't notice a difference but in games, definitely.
Depends on the card.
A good graphics card for low details on games is the nvidia 8800. I reccammend you don't get this just to be safe. To get normal to high graphics get the nvidia 9400. For high to best Graphics, get the nvidia 9800. For best Graphics, get the 260, 280, 285, 275, 290, (all nvidia).
You cannot download a graphics card, it is hardware, meaning, you have to go to the store or order one online and install it or have someone do it for you
