As of Catalyst 8.3, a.k.a. The New Beginning a.k.a. The Big One a.k.a. The Humptyback Zinglebert, it's clear that CrossFireX has picked up where SLI left off. Right now, it's a better arrangement, with a lot of advantages not limited to performance. It's just that now there's even more reason for NVIDIA to improve SLI, and when they do, they're likely to start with a hardware advantage. When is this going to happen? AMD didn't include a slide on that subject.
