That's equivalent to 16x 8x 8x with PCIe 2.0. 

Still a bit of a bottleneck, but it should still function well enough.

thanks Thanny... i guess then its good to go...

im having 2 asus direct cuii (2.5 slot) 7950s nd thinking about adding a sapphire 7950 (2 slot). the thing is i can only enable crossfire if i use two bridges. with one connected the CCC says cards are not connected. i checkd the bridges seperately , no faulty bridges there. 

when im running trifire like this i wont be able to conect 2 asus cards using two bridges. will this cause a problem and disable trifire?

No, but I don't see you using 3 2560x1600 monitors so you don't need the power of triple Titans.
