if you want profitability check out
http://get-monero.org it will redirect you to the mining pool (that is my affiliate link url shorter) but if you do not want to use my affiliate link you can use ragerx.lol
The pool has been setup by XMRstak devs, even the monero devs etc admit that the pool and its custom software ( you have to flash it to a usb and boot of the USB with a self contained OS) is faster at mining XMR then any of the current mining software available on the market.
The pool does have a 3.5% pool fee but as its 10% faster you are 6.5% up still.
The pool also has affiliate links so the more friends you get to mine xmr the more xmr you will also earn.
Check it out guys you will not be disappointed its coming out from beta today.
