For upgrading your PC, as an instance on playing games (because both are needed on games),
-Processor determine how long your game loading does, AI, and everything about process and thinking.
-Graphic Card determine graphic rendering performance of your game, how smooth it does, and how nice it would looked like.
So choose wisely, because both are a crucial for gaming PC
Graphics card, hands down
The graphic settings on games such as WOW and Crisis 2 do depend more on your graphics card rather than your processor speed :)
An AGP card functions as the computer's graphics processor.

Update your graphics card and processor. Adding RAM also helps. It may be easier to buy a new computer with a high-end graphics card and processor. There are many that are prebuilt (like Alienware) but the cheaper option would be to individually order all the parts (motherboard, processor, graphics card, RAM, etc.) and put it together by yourself.

Graphics cards are very cheap these days, even a $50 card would be much better than using the onboard graphics.
If you have a dedicated graphics card, the i7 is better by far. If you want cheap and fast with graphics then get the A8.

The i5 processor contains a very descent HD4000 graphics processor that allows gaming. It is not for hardcore gaming. An additional graphics card makes the laptop a good gaming one...go for it !!
Intel's new Core i3, i5, and i7 processors combine a graphics processor with the computer's main processor chip. This results in better video performance without an additional graphics card.
