edit:
sorry i didnt read what you said at Use minergate if you have a good cpu but for gpu try something else (maybe mining altcoins using claymore)
which altcoin should i mine then?

edit2:
i looked up claymore's cryptonote gpu mining program and it says its only supported on AMD cards, i have an nvidia gt 730.
