ANTMINER S9 or 4x RX580 8GB GPU RIG ??????

[Dukebit]

Good day guys,

I would like to get some feedback with regards to a decision that I have to make.

I am able to buy either an Antminer S9 or a mining rig consisting of four rx580 8gb gpu's for $2300.

I need to know?

*  Is this a good price ?
*  which option will be the best ?
*  which one will give me Roi the fastest ?
*  How long will Roi take on each of the two

I've read quite a lot but still very unsure of which is the better option if any, hoping that some of the experienced guys can share their thoughts.


Thanks

What are you trying to mine.
If you are going for SHA-256 coin than the Antminer s9 would beat the 4x rx580.
But if you are going with other coins like Scrypt, x11 (and types) than the rx580 would beat Antminer S9.

Regardless of the coin or algo, which one will roi fastest and which one will be a better investment?
