another 390x of course.
You can't crossfire with a 390 as far as I'm aware.
And a 290x of course.

Of course the best option is the 390x. Second best 290x. I wouldn't even try the 390. And you shouldn't need more than a 1000 watt psu. Just make sure it's from a notable brand like evga or something like that.

AMD Crossfire you can crossfire any graphics card in its GPU family architecture, for instance a 390 can crossfire with a 390x, and since the 290 series cards are the same architecture as the 390 series you can crossfire those together also. AMD crossfire is more lenient than Nvidia SLI. The best option would be to Crossfire the same card of course but you have options. With PSU like the guy above me said 1000W is the best option for that. Hope this helped!
