Will my old video work at the same time as a new PCI-E video card?

I have a ATI Radeon Xpress 1100. If i add a ATI Radeon X700 128MB PCI-Express Video Card will they both work in sync so i can get better video quality while gaming or will it replace the old one?|||no



If u want to do this using ATI u have to change ur board and get 1 which supports "crossfire"...then u have to apply 2 graphs cards of the same time of ATI brand.
