Is this for gaming? If so, it'll only make a 5-10 fps difference maximum. It's not worth it in my opinion. if you are going to upgrade i'd recommend going to 1866 minimum
5-10 fps? Thats generous, maybe hit 5 in a very CPU intensive game, otherwise most of the time it would be barely noticeable. If you're upgrading to a larger amount of memory, sure buy as fast as you can get for your board, but otherwise don't waste the money.
