Good on them for testing to see if that worked but...
They gave people wrong advice when it was staring them right in the face the entire time.
Those graphs from Trine 2 are a textbook example of a multi GPU configuration doing the worst possible thing and they simply swept it under the carpet with the excuse that because the frame time is so low anyway that it doesn't matter. What a way to totally avoid having to be critical. If that behavior happens in any game that you don't pull north of 100fps average on it will feel like a bag of crap regardless of what your average FPS will tell you.
And before anyone tries to call me out. I've been playing on a triple monitor setup and suffering from these exact problems for at least 2 years before either AMD or Nvidia even started supporting multi monitor configurations. This is make or break stuff for people who are using multiple graphics cards on higher end setups as well as those looking for a cheap boost in power by getting a second card and these guys just sweep it under the rug like it doesn't exist.
They also have no idea why Skyrim didn't benefit from the Crossfire? It's because it's not GPU limited.... /facepalm
Originally posted by CowboyHat Any idea if it will crossfire with a 7950 as well?
If it CF's with a 7970 (and I believe they did), they should CF with a R9 280X, unless they did something funky in the driver to explicitly disallow it (which wouldn't be the first time).

AMD has long taken the approach of allowing people to use CrossFire with completely insensible configurations. So I'd be surprised if it can't be done--but I'd also advise against it. Nvidia, on the other hand, restricts SLI to situations where it makes at least some technical sense.

You can't reason someone out of a position they didn't reason themselves into.
