The processor are so much small in size but the size of the graphic card are are so much bigger in size as compare to the processor. I think now is the time that graphic card work can be taken up by the processor it self. For example i7 contains 4-6 cores. now four cores for processing and other two cores for graphic works. I think this could be possible if companies like intel or amd works with the graphic card manufacture like xfx or ati to build a such a processor.
