Best motherboard to host up to 4 NVIDIA rtx 2080ti

[wienholtw]

I am planning to setup a desktop for deep learning, starting with 2 NVIDIA rtx 2080ti and extend to four at a later point in time. As I need 36+ PCIe lanes and 64GB+ DDR4 Ram, I wonder which motherboard is suitable?

Depends which route you are taking, Intel X299 or Threadripper X399???...Both these platforms can provide sufficient PCIe lane with the Threadripper having more available...

2080 Ti does not support 3-way and 4-way SLI. How will you bridge four 2080 Ti's ? There is none available from Nvidia. Or were you talking about Directx12 Multi-GPU? That's different then.
