This is sort of a

This is sort of a random computer question for “da boys.” Lets say that I do indeed get the nForce board, would the built in GF2 work “automaticaly” and/or what would happen if I put in the video card I have now? Would it get confused and use one instead of the other? Would it use the add-in card as extra? Would I in a sense have a “duel Geforce 2” or one I have to pick one? These are things that non of the reviews I’ve read seem to be addressing. Any ideas? I just don’t want the short end of the video card/Mobo stick. I’ve had plenty of Mobo/Gfx card problems before (*cough* TNT2 and Asus *cough*)
