No matter what you are doing on a PC if you want to start the computer and see a display on the screen, you must have a graphics card. Which means that if he has a working computer then he has a graphics card. Some motherboards come with graphics cards built into the board, but either way the computer has one. Now knowing if your graphics card is powerful enough for some games is a different task. You need to know the game you want to play's system requirements, and the computers specs such as ram hard drive space and video card power.
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.
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.
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.
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 will need to set up the grphics to minimums and then test each setting to see how the graphics react. However, it may also be that your RAM is to low for the system files.
A graphics card is a part within your computer that powers the graphics in games, the video monitors, rendering and generally displaying things on the screen. Some motherboards have something called "on board graphics" and that means that the graphics come with the motherboard.
Although the Intel 4400 graphics card is not ranked as one of the best for gaming it is good for games.
