Graphic cards (VGA) with Intel chipset is designed for low power, so most laptops have integrated graphics have a longer lasting battery and less heat is more important for the majority of laptop owners rather than graphics performance. There are many desktop motherboard equipped with Intel integrated graphics. This is done to make the cost of a PC to be cheap. But fortunately there are still Graphics Port Expansion so you can add a decent graphics card to upgrade. Modern games require a much greater power than just graphics for HD (multimedia).
Intel Core i series (Core i3, i5, Core i7) with Intel graphics are good for the performance of Windows, the Internet, and watch movies, but for 3D games modern still less remember not supported by a good driver as well as the absence of the anti aliasing. for modern 3D games, graphic cards (VGA) should result in a full screen 3D pixels in real time, it takes a lot of power to run graphics.
While watching the video, the Internet, and running Windows, it takes very little power. maybe Intel HD integrated graphics card is best, but not for serious 3D gaming. Games such as Battlefield Bad Company 2 and COD Modern Warfare 2 and World at War with a low setting can still be handled at the Intel 4500HD. If you find out about the performance of each series intel HD, I have summarized it.

Pixel fillrate
Indicates the number of pixels that the Graphics Processing Unit (GPU) is capable of writing in video memory in a second and is measured in megapixels / s or, in newer cards, Gigapixel / s. It corresponds to the product of the clock frequency of the graphics processor and its number of pipeline.
Texel fillrate
Indicates the amount of texels (fundamental element of a texture) displayable in a second and is measured in Megatextel / s. It is equivalent to the product between the pixel framerate and the number of texture applied to each pixel from the processor.
