Performance actually scales pretty nicely with the clock speed increases, but we have to wonder how much better it would have been if the NB portion was able to be clocked higher than 2 GHz. If I was willing to do a bit of hex editing on the motherboard BIOS, then I would have the ability to increase that multiplier. However, myself and the vast majority of users are not exactly comfortable messing around with the BIOS at such a low level and potentially bricking their motherboard.
