How can I know if my computer can run multiple video cards in SLI?

Question

i have a dell inspiron 530

it has an integrated graphics card that a computer expert on yahoo answers told me is not taking up one of the slots (true? or not?)

and 1 PCI-e 16 slot, 1 PCI-e 1 slot, and two PCI slots

also, if i bought one PCI-e card, and one PCI card, could they run in SLI? finally, would the PCI card slow down the PCI-e?

thanks in advance guys

Answer 1

The integrated video card is in the actual motherboard, so no it is not taking up one of the slots. SLI video cards must be compatible with each other in order to be used, as far as i know there are only PCI-e SLI compliant video cards and no PCI.

Answer 2

if you have integrated graphics it does not  take up a pci-e slot.   there is a such thing as a pci graphics card. you probably won't find or hear much about it because it's old technology basically obsolete.  to use a pci graphics card would be taking a step backward and it definitively wouldn't run in SLI.
