Will you use Jarvee on it? If yes, you can contact support and tell them how many accounts you will use and which social networks and they will tell you some general recommended specifications that are required for running some amount of accounts smoothly.
@Luca has made some good suggestions, I would just add that it’s important that you know how many accounts you want to run, and depending on that you should be able to decide what setup exactly would you need. It’s best that you contact their support, explain to them how many accounts you want to use and they will instruct you.

Consider a decent GPU as well in your setup if you are editing content on your own for platforms. You’d rather use 20% of a 8GB GPU in PS, LR, PR or any other Adobe software than to give away 50-60 or even 70% of the available RAM for a fast work flow.
