One motherboard can only have 1 graphic card, unless is nvidia
series (i forget the version liao)
moreover, each mother board only have 2 slots max where to find
3?
Even you have 2 different graphic cards, they still process the
same thing, please, you only have one motherboard... just like a 2
lane traffic, one is go, one is come, no break point and no space
for 2 and more car.
Quit your thinking about having a split video...
