i am going to hopefully buying another x1900 series card for some crossfire action, and so i am asking has anyone had any experience with it working on the p5b-deluxe for example? the only thing i can find really is that custom pc tried it out and in 3dmark 06 it matched the 975x boards.

apprently on the 965 you get 1x16 pci-e speed lane and the second slot reduces to x4 which again isnt a problem because the card would have to be pushing out more than 1Gb/s to push the x4 speed lane to the limits.]

I would go for that Abit board, but i belive if you crossfire it you cant then use an X-FI sound card even if you have a water block on it?

any help or ideas would be excellent
