Intel is for multi processing. AMD is for focused processing, such as gaming.
Intel is for people who will be running many programs at the same time, such as a graphics artist. (5+ windows? & heavy programms)
AMD is more for media, gaming, etc. As these people will only have 1 ~ 4 windows open. (1 heavy program, with web browsing etc.)
Intel graphics card is horrible for gaming. They are not made for gaming, so get either an ATI or Nvidia graphics card. Either will be better than Intel.
