Nowadays mining is not an option I think. Because the time when you should start to mine has passed. People now are united in mining pools. They have power that is impossible to beat for individual who just want to get some BTC with his GPU. And the whole mining sphere is belongs now to these pools with huge mining farms. And you will need enormous amount of money to just even take a visible part in these sphere. So I advice you to not mine now and just invest your money. Or mine some altcoins if it possible. Because if you do some researches you will understand that I'm right.
