2.0 x16/x8/x8 is fine. As a result, 3.0 x8/x4/x4 is fine. It's not until you choke the lead card that it becomes an issue, and it's still a matter of resolution and FPS.
I'm also still waiting for the day when Red gets beyond the 5760 horizontal and uses bezel compensation like everyone that uses Eyefinity, because it will make an impact to FPS and no one plays without it (I find all reviewers guilty of this). In portrait it makes an even bigger impact, with the correction being on the 1920 axis rather than the 1080 one. My own correction in portrait adds 322x1920 to the total res, which is a full 10% bump in overall resolution.
Also, if 290X Crossfire is geared at 4k, then quad is geared at tri-1440 or tri-1600. These would be the relevant resolutions for the tech used. Tri-1080 is a bit of a waste.
My feelings on the matter anyway. If you're going to make one of the most beastly computers in existence, at least use it to its potential.
