I just installed a new SSD and put Mint 17.3 on it. I'm shocked how fast this thing is. I have a 5960x and two 980 TI Hydro Coppers. The nvidia driver works pretty good so far, but I don't see anything about SLI.

I was researching the same thing... I'll let you know what I find.

Yeah? But does it help? Or how well does it scale?

I don't have any experience but last I remember it didn't really exist or not like it would in Windows. This is all with Nvidia proprietary drivers.

I didn't think it worked but I thought it'd be pretty cool if it did. I definitely need to switch to Nvidia. My 7950 is way to slow.

Its game profile specific .. which typically means no. That technically means it works but usefully .. probably not at the moment. It might become more of a thing with the Vive around the corner.

This is what I'm finding out. It does work and it is on, but finding game profiles is another story. So what good is it?

I used to run dual 270x's in crossfire under linux. In games that can leverage crossfire, it works great.

The only catch is that you can't set up multi-gpu through the Catalyst Control Center software (amdcccle), you instead have to use the command line program (aticonfig).

This all assumes you use the fglrx/AMD driver, rather than radeon or another open source driver.
