Choosing a motherboard for a new PC
Plans to assemble a new PC, while determined with all the components, the main:processor - AMD Ryzen 9 3950X
two graphics cards - SAPPHIRE AMD Radeon RX 5700XT , 11293-03-40G NITRO RX 5700XT 8G
However, there was a problem.
I can't find a motherboard that will work in 16 - 16 mode for this processor and videocards. The best that was 16 - 8. Therefore, I ask the fumbling GURU to suggest a suitable motherboard. The price range is not important.

The 5700xt doesn't have CROSSFIRE X support, and combine them just for the sake of direct x 12 and Vulcan.

My mistake pointed out the wrong processor.
The AMD Ryzen processor is 9 3950X and it holds 32 lines, according to its characteristics.

3900- 3950 is not much different from both 24 pci e lines
So you can close the topic and not look for it.

Let's start with the fact that the 5700xt has no crossfire support, and you have to look towards NVIDIA and NVLINK, besides:
There are no such boards under THE AM4 regardless of the chipset.
The latest before ryzen boards for consumers at AMD with this feature is the 990FX chipset for AMD FX processors.
PEG slots with two see-ins on any AM4 board will run in 8 x8 or below. there are no boards on 16 x8 either.
there is nothing like that on the current desktop sites 1151v2 and 1200. either one x16 card or two 8 x8 or below.
If you want a 16 x16 on the modern iron, look towards the boards for the intel lga 2066 platform on the chipset x299. any i9-79xX/XE processor, 99xX/XE, 109xxXX/XE (preferably 10 series), but no less than ten cores.
Or
amd platforms on X399 chipsets or new TRX40s for the first, second and third (preferably third) generation of ryzen threadripper processors. There's already a CPU model that doesn't matter as far as I can remember, and you can bet with any number of cores. just know that the third generation threadripper under the new CHIPSet TRX40 and the TRX4 socket. the first and second - under the chipset X399 and socket TR4.

As far as I know, the new line of video cards has not yet gone on sale. Accordingly, some of the best AMD video cards at the moment should not support the technology CROSSFIRE X. And if so, what graphics card from AMD with support of this technology can recommend (desirable range up to 50k)
P.S. Previously was not interested in video cards AMD (almost not fumble).

I had two RX580s in 16x8 and there were norms, and what's not comfortable with 16x8?
Tiobat
She won't be like that. The RX5700 can only in x16-x8. The older generation generally only x16-x4 might.

I'm ready to review other graphics cards as well. Simply RX5700 showed good price and quality ratio

Better look for NVIDIA map.
SpoilerOn after the release of RTX 2070 Super it became known that NVIDIA has restored support for the NVLink SLI for this model. But the Radeon RX 5700 XT and RX 5700 lack CrossFire support. If you connect two cards to the newest board on the X570 chipset with PCIe 4.0, you won't find an item in the menu.

I support, if the funds are not limited, then 2080 super/ti. Although if I were you, I'd wait for a new generation.

Thank you for taking the time to address my problem)
Your recommendations have been helpful and I'll take them into account, although it looks like we're going to have to fundamentally rethink the BUILD of the PC, sadness (((
And I would have waited for ddr5 and obviously in this mom will be new chips, the more confirmed the development .
really the couple is not even among the workstations at 570. you can see the limitation of the chipset
Amd by the way that to say something kind of favored cross-fire so that such a term is no more. and the nvidi is not yet express 4.0 cards kind of as yet so that 16-8 8/8 yet pump cards to the maximum I understand (although perhaps the controller itself will limit the speed to 3.0 if it sees 3.0 card.
