5820k or 2700x in home server

[kolere23]

So i recently bought a computer used from a friend. The spec list is below. I am trying to decide if i should keep it as my home server, which was the intended purpose of the purchase, or if i should use my 2700x from my gaming machine . I am new to servers and the use but i would like to make a plex server and host an FTB server from it (the server would have about 10-15 players at max).

 

Just to clearify, if the 2700x would go in the server i will use the 5820k in my gaming machine for example

 

Spec list: 

Intel core i7 5820k

16 GB DDR 2400mhz 4 ram

MSI X99 Deluxe MB

Random 500 watt PSU

GTX 980 gpu (i am swapping this for a gtx 460 just to get display output, and i am selling the 980)

well the 2700X is more powerful so I would use that in the gaming machine personally

You don't need that much power to host FTB.

Just use the 2700x for game.

You don't need that much power for an FTB server but I guess the 5820K

As others have said you don't need loads of power  i have an I7 4770s in ours with 16 gig of ram  running windows server 2012 R2
