There is not much difference between 1030 and 1050 when it comes to mining reward per month, they are less power hungry so no matter what your electricity bill is per month you won't feel a thing, it's better to use a pool or software with low payout because it will take longer to reach minimum payout
Using a pool or software with low payout is not what is needed here cause mining with GT 710s and 1030s is never profitable if put the time spent into consideration except if the coin is newly created with future promising.
It better to get a cheap hardware miner than using the GPU this day thats the reason people don't use the equipment OP spoke of.
