Hes right, no you cant.
SLI is possible because of PCIe's extra bandwidth, PCI is uber slow so it is 100% impossible.

if you have a pci_e slot then you have a port capable of 2x over agp8x. What pci_e card could you have that isnt somewhat rockzor, or even slightly better than anything agp8x? I cant imagine...

or do you have some crappy pci_x (agp bus) wanna-be pci_e card?

If your motherboard has SLI, then you can SLI graphics cards, but as I understand it they both need to be the same type. Also SLI can slow down games that don't support SLI, and the proformance difference isn't that massive anyway. You are better off getting the lastest top of the range card, then SLI'ing anything.

Really? I thought it always would double preformance.

No there is alot of overhead, it takes more bandwidth from your bus then the bus has to offer. Also as I said, the game has to be SLI compaitible, really, you are better off buying the biggest, fastest graphics card you can afford then grabbing and SLI'ing them. It was the same when Voodoo where running their cards in union.
