Supposedly, yes. But I've used B and G routers and don't notice any difference personally. Many people feel the same way I do. If there is a difference, it's not much.
Regardless, I don't think there will be a difference in the cards, only in the routers. So if you have a G router it might go a little further assuming you are using G cards....but if you have a B router, you have no need for G cards (they won't go any further, or faster).
