And leave the existing card installed also, then no. Your motherboard cannot accommodate the extra card as you only have one PCI-E slot.
i've got a new dell inspiron 530 desktop with a ati 2600 hd xt 256mb video card in it. the card has dual dvi connectors.
i have another video card ... the EXACT same. same model # and all.
can i install this card to run more than 2 monitors? i want to run 3 monitors total
thanks in advance
