The answer is completely subjective,it's all your interest.Personally,I would advise you to mine PoS based coin or the existing coins which are moving towards the trend.You have a descent configuration.Check out nodeJs based software's for mining good coins with low electricity consumption.You won't really be getting a much out of it but if the coin does have a future,you will surely hold a lot.
There are web sites opened for this. It does not make much sense to me to think of constantly mining a different coin. It may be more logical to make a decision on a coin and its mining.
The websites can always get paid and promoteshit coins.They are not a reliable sources of information.
