The reason why I go out on dates with someone is to determine if we're compatible or if we can look forward to a future together. Faith does have an impact for me because I want the relationship to be God-centered and if the other person knows God in a different way, then there would be a problem from the get go. There are religions that do not allow their members to marry outside of the church. Hence, it would be futile to date a member of that church unless you're willing to be converted to another religion or he is willing to leave his. I am currently dating a guy who is from the Catholic faith while I am a member of a Christian church (and a former Catholic). He is very much willing to be converted to my faith and has been attending church service for the past weeks. Hence, the difference in religion has no impact at all in our case.
