I. Introduction.
Your computer is bought a long time ago ?
Your computer is not powerful, but your image processing programs or games require powerful configuration ?
You don`t have enough money to buy a new powerful computer, or its price is too expensive?
Why don`t you think to upgrade your PC by installing new graphics card ?
II. Specification. II.1. Definition.
A graphics card is also referred to as a graphics accelerator card, display adapter, video card, and numerous other terms.
It is an item of personal computer hardware whose function is to generate and output images to a display.
The term is usually used to refer to a separate, dedicated expansion card that is plugged into a slot on the computer's motherboard, as opposed to a graphics controller integrated into the motherboard chipset or "integrated graphics processor" (IGP).
II. Specification II.2. GPU
II. Specification II.2. GPU
A GPU is a dedicated graphics microprocessor optimized for floating point calculations which are fundamental to 3D graphics rendering.
The main attributes of the GPU are the core clock rate (250 MHz-650 MHz) in modern cards, and the number of pipelines (vertex and fragment shaders), which translate a 3D image characterized by vertices and lines into a 2D image formed by pixels.
With typical user, when they buy new graphics card, they only care about a ram`s capacity of graphics card, but the most important component which decide the speed of graphics card is GPU.
II. Specification II.3. RAM video
If the video card is integrated in the motherboard, it will use the computer RAM memory (lower throughput).
If it is not integrated, the video card will have its own video memory which is called Video RAM or VRAM(from 128 to 1024 MB).
The VRAM was based on DDR technology, standing out DDR2, GDDR3 and GDDR4.
The memory clock rate is between 400 MHz and 1.6 GHz.

II. Specification II.4. Outputs
The most common connection systems between the video card and the computer display are:
VGA(Video Graphics Array)
DVI(Digital Video Interface):
II. Specification II.4. Outputs
S-VIDEO(Separate Video)
HDMI(High Definition Multimedia Interface)
II. Specification. II.5. Motherboard interfaces.
Today, popular motherboard interfaces are AGP ( Accelerated Graphics Port ) and PCI Express®.

III. How to intalling a graphics card.
Undo the screws on the two card blanking plates at the back and hinge up the metal plate:
III. How to intalling a graphics card.
Insert the card and push it down into socket.
III. How to intalling a graphics card.
The card seems to pull over to the right as shown below, this would mean that the TV out would be blocked, so I had to push it quite hard to the left as far as I could.
III. How to intalling a graphics card.
As you can see below the TV out is just about free.

IV. Glossary
Direct3D: Released by Microsoft in 1996, is a component of DirextX. Designed to be used exclusively in Windows, it is used by the majority of Windows videogames.
OpenGL: Developed by Sillicon Graphiccs in the early 1990s, OpenGL is a free, open, multi-language and multiplatform API.
Scalable Link Interface (SLI) is a brand name for a multi-GPU solution developed by NVIDIA for linking two (or more) video cards together to produce a single output.
CrossFire is a brand name for ATI Technologies multi-GPU solution, which competes with its rival nVidia`s Scalable Link Interface (SLI). . . .
