Why not just save for a 4870X2, and then add another when necessary. Also, if the system in your sig is your planned build for the summer ... may I suggest, do not get an AMD CPU. I am not a fanboy. No matter how you slice it, that will severely limit your performance in games, unless AMD pulls a magic rabbit out of the hat. And with nehalem right around the corner, AMD is poised to be all but annihilated.
