It's important that I mention that a 750 ti isn't good (as in strong/efficient) in mining ANYTHING. It's a bad card for mining and you shouldn't mine anything on it if you want profitability or any decent amount of coins.
With that said, just enter on Google "cuda miner + (coin you want to mine)" and you'll most likely end up with a mining software made for Nvidia cards for that particular coin/algorithm and a guide on it.
