you want the X79 chipset for that, even the cheap boards have this feature.

however on Z77 and Z87 for instance you need a board with a PLX bridge chip, those boards aren't cheap. Some examples are the G1.Sniper 5, Z87X-OC Force, and Maximus VI Extreme

I looked at the Maximus VI extreme for Z87 but even that doesn't do that according to what i've found.

You don't really need 3.0 @16x on both cards. 3.0 @8x is enough for graphics cards available today. Heck, 2.0 @8x works wonders with most of them.

Hey you are right! and there is a reason ASUS does that, they did that on the Maximus V Extreme too.

So testing out PLX 16x/16x versus native 8x/8x, some cards perform 1% better on native, so ASUS made it so that unless you run 3 cards you get 8x.8x native. I did some testing, and back with the NF200(old style PLX for PCi-E 2.0) this made sense, but now one can say it doesn't matter much.
here is the review where i did the testing: http://www.overclock.net/t/1262935/g1-sniper-3-review-plx8747vsnf200-circuit-analysis-ln2oc-core3d/0_20
The testing was done with PCi-E 2.0 review, i worked really hard on that review just to test that theory out.
IMO if you have the money buy one(a board with 16x/16x PLX) and if it doesn't perform better then return it and keep your current board with native 8x/8x.
