Well, yeah. Shared interests matter. Some people think they don't, but it makes things easier when you want to figure out something to do with your bf/gf. That kind of surface compatibility isn't EVERYTHING in a relationship, but it is important. I'd date somebody who didn't share my interests, but I better really enjoy spending time with them, y'know? 'Cause I mean, if somebody doesn't have any of your interests, what are you gonna do?
...Yeah, okay, but assuming you want a relationship that goes beyond the Spring Break level, what are ya gonna do? Non-geeks don't "get" things like needing/wanting time to read/play games/watch anime, because they don't get the appeal.
I'm dating a moderately geeky girl (not a huge gamer, but she's into a lot of other things I like), and I think it helped the most at first, when we were kind of uncomfortable around each other. Sitting down to watch Star Wars, or Futurama... It kinda put us both at ease, y'know? When I'm doing something I'm comfortable doing, it helps get past the awkward stage of getting to know somebody romantically. At least, I think so.
