Before making a decision consider the downsides... What if the new company has problems and they need to lay you off? What if you new boss/team mates are jerks and keep making your life at the new company hell? ... What if you need to leave the new company a month after you join it. New things are exciting, because they are different. But do remember that they have challenges as well. While the above will likely not be the case for you, companies might think of you as not being loyal and might not want to invest in you much. I personally would give my company 18 months at the least, and if I am getting restless I would have a nice long chat with my boss before leaving.
