Here is the review Donut is talking about http://www.techpowerup.com/reviews/AMD/HD_5870_PCI-Express_Scaling/25.html
x4 lane has plenty of bandwidth for 2 5770 in crossfire, should he choose to go that route.
The problem with the 'scaling' article is he did not run CrossFire (and it was an Intel P55 chipset with the controller on-die). 'Theoretically', you have twice the overhead on the controller with CF and that may well impact scaling. It's anybody's guess at this point --- especially with an AMD arch.
Wizzard said he was working on a follow up article by running two cards in CF with one at 'x4' but I've yet to see an article (it may be out there and I haven't seen it).
As long as it's been I think his theory might have gone to crap - LOL
