My current girlfriend is not a gamer. Neither are most of my former. I dated one girl that I met at a game and it ended a month later in drama and heartache. I've had my own games disrupted or even put on hold because of three other relationships where both members were in the group and the relationship ended.
Despite all of that: I still have the geek-girl fantasy. The idea of meeting a woman who enjoys tabletop gaming, MMO and FPS computer games, sci-fi/fantasy books and movies, and so on... I convinced myself years ago though that while hot geek girls certainly do exist, they are almost always already involved... and sometimes with guys who aren't geeks themselves. *horror*
