Assuming that you are asking for mining software, IMO - the best profit-based mining program is from NiceHash: https://miner.nicehash.com/

It is by far the best mining program, it does benchmark your hardware prior to auto-selecting the right algo for them and also switches algo (based on market), so that you get the max.profit.

You can also find an approximation of monthly profit/hardware with their calculator: https://www.nicehash.com/profitability-calculator

Good-luck
