Ok guys..... Onboard video chips have direct access to the cpu data lines, memory, and all that. That data transfer runs at the full, native speed of the chipsets. Additionally, the video chipsets are often integrated directly into the north/south bridge chips taking the GPU that much closer, logically and electrically, to the CPU and OS. Even the fastest PCIe/PCIx video cards will be getting their data through buffered motherboard connections/card slots. These are at least two, and more often three electrical jumps from the north/southbridge chips through which the CPU and OS communicate. Lots of potential for wait-state there. So assuming that the integrated video chipsets are capable of competetive rendering and frame rates, and the most recent ones are, there is no reason to aussume that on-board video will be slower than add-on cards. There is a lot of potential there for on-board video to be faster than add-on cards.
