With a 750ti it would make most sense to mine a cryptonight v7 coin and then exchange for priv...  my msi gtx 750ti gaming makes 286h/s with a little OC of +250 for clock and +600 for mem... if you have a decent cpu mine is fx-8320e (320h/s) you can make over 600h/s and with that you can mine over 1800 XTL per day which are 6 sats per piece... if you exchange them for priv you get almost 6-7 priv per day... if you mine priv directly you get next to nothing because priv is mined best with asics and the 750ti is not a fast card... the difficulty is too high...
