Thats a stupid poll! as Intel and nVidia are used on different types of components. Intel could be the CPU and a Nvidia could be for the graphics card...
or they could all refer to graphics chips, but being in the motherboard catagory it's easy enough to tell that motherboard chipset was the intended question.
Well even that said, its kinda hard to judge chipsets spread across an entire platform as wide as the company itself. Interestingly you also left out AMD and ATi .... my fav chipset is prolly 440BX
