cross fire can I?

yes hello to all my just bought foxconn mobo to a crap on me so i am looking for a replacement right and i was just wandering can i crossfire a pci-e x 16 with a pci or pciE x1 to a pcie x 16 or any of the aforementioned in any combination because the board that i want to get is the Asrock P5B-DE ( 40$ brand new)and it only has one pcie x16 but has two pcie x1 and 3 pci slots. so any help will be much appreciated
THANKS IN ADVANCE

Square peg round hole ruben... Videocards will not fit in x1 slot. They are made for x16 slots. If you get a riser card to go 1x to 16x, you would severely slow down the other video card in the x1 slot.

So again, no. If you want to SLI/CFx, you need a board with TWO x16 sized slots.

okay thanks earthdog
