Need Help in My build

[Alaa SaM]

Hey All, i'm trying to build another PC for my work.
I render on corona and it's CPU rendering not GPU so that's is what i'm thinking about and i would love to take some advices.

 

const components:

1) Corsair spec 6 (mid tower)

2) Corsair 2*16GB 3000MHz

3) 750w 80plus

4) WD 2TB black

I won't buy a GPU but in future will get on

 

The problem is processor and motherboard... idk which choice i should take? 

First: (Threadripper 1950x) with ( Asus ROG STRIX X399-E GAMING Socket TR4 Motherboard ) >>>> Cost :17500

Second: (Intel Core I7-8700K Coffee Lake 6-Core 3.7GHz) with ( MSI MPG Z390 GAMING Plus Socket LGA 1151) >>>> Cost: 10000

Third: ( AMD RYZEN 7 2700X 8-Core 3.7GHz (4.3GHz Turbo) Socket AM4) with ( Gigabyte B450 AORUS PRO WIFI Socket AM4) >>> cost: 9300

 

Help me or Guide me... i'm saving from 5 years and have money for all choices but I don't want to spend extra money on something i will not use So does it worth ? the threadripper
