Meh. Not sure what he's talking about there. FiringSquad showed the exact opposite as 5870 Crossfire was out in front in nearly half of the benches, despite 5870 getting beat in almost every test by 480.
With this stuff, you really just have to consult several different reviews and then pass judgment. People's setups can differ a lot, causing lots of variation.
My 5xxx rig is still in build, but I've been back and forth between Crossfire and SLI over the past few years, and my impression is that they're nearly identical to each other. Scaling is very similar, as most of the benches show.
