The main upshot of the increased Front Side Bus is that it stops processor clock multipliers spiralling out of control. Take the Pentium 4 Extreme Edition for instance this is a 3.4GHz chip, so with an 800MHz FSB you're looking at a clock multiplier of 17x. Using a board with a 1066MHz Front Side Bus allows you to reduce the clock multiplier of a CPU without reducing its frequency. In fact, Intel's new Pentium 4 Extreme Edition runs at 3.46GHz, but only employs a clock multiplier of 13x obtained by dividing 3460MHz by 266MHz.
