Isn't this very much a case of the academic grass being greener? You don't like how your bachelor's has so far turned out and you would much rather jump the gun and get involved in an area which seems more appealing but which you haven't begun research in yet?
If you are in your first year, it's very common for students to feel disillusioned with their courses. This is why there is so much doubt, soul-searching and drop-outs among first years. I know in my own case, my BA was not what I expected it to be and I considered leaving but I stuck with it and graduated. If this is how your bachelor's has turned out, what makes you think a master's would be different?
I would advise the same for you - stick with it. Remember that you are studying a discipline, not one cherrypicked aspect of it, and your love should be for that discipline as a whole rather than those parts that seem more illustrious. Of course there are parts of any course which we favour more as researchers, but part of the academic ethic includes working through those, since you never know when they may prove useful.
I would caution against going to your professor. I don't think it will be looked on in a favourable light unless you are extremely bright and different to other students. And even if you were, there's little reason for them to make a special difference for you, unless you can put forward an extremely compelling case.
