I don't think you will see major changes immediately, getting a great score, like most good things in life, take time, but if you are consistent it will reflect on your score.
Also, it also depends on how much credit you have from all your cards combined, if you have 200K from all your cards in total and spend under 2000 a month, i.e. less than one percent, I don't think it will have any affect on your score. If I remember correctly, and CMIIW it only starts having an impact by 10% credit utilization.
