Can you do a SLI effect between a video card and the graphics card built into the motherboard?

I just wanted to know if you can do some kind of SLI effect between the graphics card build into the motherboard and the external video card. From my understanding the motherboards graphics card takes some of the memory to use it or something along thoes lines...just curious..|||Yes it is possible. For ATi graphics card it is called HybridCrossfire and for Nvidia graphics card it is called HybridSLI. For that u need to have HybridCrossfire or HybridSLI compatible graphics card and HybridCrossfire or HybridSLI compatible built in graphics card. If u have an Intel built in graphics card, forget it.|||No because the graphics on your motherboard are not the same as the graphics card that you have pluged into your motherboard. You have to have the same graphics card to use SLI or cross fire.
