im having about 30-33mhs i just wanna know if it's the limit of my card,
Yes, that's about the limit of your card. You can easily check that if you go to
http://whattomine.com/ and look at the mean values of the Hash rates for the various crypto-algorithms.
For
Ethcash and
Nvidia 1070 Ti, this website predicts 30.5 MH/s.
As makomako suggested, you might want to try other algos, like
Equihash or
NeoScrypt. Currently, they seem to be more profitable for your GPU.
