The rig will be an upgrade for my present rig which is: i7-4790K, Asus Z87-WS, 2x8GB DDR3 2400 RAM, 4 GTX 1070s with AIO coolers. Blender is not scaling 100% as it is supposed to and I was wondering if a CPU with more lanes will fix that.

Rig #1
i7-6850K, ASRock X99 OC Formula/3.1, 4x4GB DDR4 2800 RAM, 4 GTX 1070s with AIO coolers.

Rig #2
Threadripper 1950X, Asrock X399 Taichi, 4x4GB DDR4 2800 RAM, 4 GTX 1070s with AIO coolers.

Rig #3
i9-9900K, Asus WS Z390 PRO, 2x8GB DDR4 3400 RAM, 4 GTX 1070s with AIO coolers.

Thanks in advance for any help!

Your specs for the followup systems are all over the place. You should look into DDR4-3200Mhz ram kits for the TR build. Also, 4 GTX1070's? You sure your PSU can handle all the hardware? + TR would be a good route but not with the 1950X, not with all that's come out from AMD since then.
DDR4-3200Mhz is doable. Do you think that two dual channel kits will work with quad channel platform? I saw a affordable 3400Mhz kit but is dual channel. My PSU is EVGA 1300W gold PSU so yes it should handle the hardware. What Threadripper CPU do you recommend instead than the 1950X?
