We dont know that for sure. We dont know what kind of bandwith a single HD5870 will need. And we dont know what AMD does to minimize the overhead.

What about CF / SLI setups that work on 8x config's. Like the P55 boards ? They should have the same problems then of not bigger.

We cant say anything about it untill the cards are out. Then we can do tests by overclocking the PCI-E bus so see if you get big performance gains. I think the PCI-E bandwith wont be a problem on 2560x1600. Especially with AA en AF. Then you can use all the horsepower you can get.
