If you can afford it, going with a threadripper is a good idea imo, since the smallest one (1900X) is available for a decent price ( ~ 280 € in my country) and they boast 64 PCIe lanes, which is more than a workstation Xeon has. Drawback is that the boards are quite pricy and there are very few to choose from.
From doing a quick lookup I would say a Gigabyte Aorus Pro AMD X399 (https://www.gigabyte.com/Motherboard/X39...PRO-rev-10) has enough connectivity for 8 cards, but it is necessary to check the details (e.g. does every m.2 slot connect to the PCIe interface, or is it SATA only).
Another plus is that you have 8 RAM slots, which scales well. Also here in the forum it is recommended to have RAM >= VRAM to prevent CL_OUT_OF_RESSOURCES errors.
