Its not that bad really...As long as you get a good Mobo with nice overclocking features, bumping up the Fsb wont be difficult at all...only bad thing is that if you push it high it increases the ratio speed of the pci slots...but this can be avoid by getting a Mobo that has a ratio control, which multiplyes you fsb buy 1/3, 1/2 etc etc, this can help alot in keeping a stable rig... =Drew
