Compare VGA Quality and Usage
I take it you'd like to compare the ATI graphics cards and the NVidia graphics cards with Intel's integrated graphics cards, right? Integrated cards have not been able to provide better benchmarks when compared to discrete graphics cards. A given Intel integrated graphics card won't be able to match the performance of a given discrete graphics card release the same time. While the latest Intel HD graphics cards can handle 3D games well enough to be playable, discrete graphics cards can provide better frames per second, higher resolutions as well as better display overall. So if you won't be playing too much games or if you're not too particular about eye candy, you can opt for an integrated graphics solutions. But for good gaming experience overall, I would recommend you get the AMD or Nvidia graphics cards.
