Care to explain a bit more?
Generally speaking, people choose to use a discrete video card for better gaming experiences or better post-processing on interlaced video material.
So far I have not seen any on-board graphics score perfectly in HQV (SD and/or HD) benchmark.
Most people think HD means bluray, which can actually be handled adequately by newer on-board graphics (AMD 780g or Nvidia 9300), is more demanding on the video card. But processing and up-scaling you DVD collection to a higher resolution is demanding as well.
