Hi there, welcome to the forums!
Here are the official recommendations from the FAQ:
The brands you choose are totally up to you, but I usually go with ASUS for motherboard, ASUS video card (I use a GTX 980 from Nvidia, but an AMD card will work just as well), Intel CPU, and Corsair or Kingston RAM.
To run multiple programs at once you will want to get 16gb of RAM. 8gb will work for a couple of programs open at once, but 16gb or more is recommended.
