Some people have had success oc'ing system busses. Im absolutely against it. They are not as stable, and if
it all goes south, so does you mb, and cpu and well, what ever it wants to take with it. I myself got in a little
too deep on the MacMod Server Mod, and toasted the board and cpu. Everything else seemed okay. We learn
from mistakes but your's could be an expensive one and I already had replacement parts waiting. You may want to
look at some cpu upgrades (which use newer cpus, but are still with the fat cache) or go all out and buy a G5.

By the way, I was all for taking mine to 1.5dp, but could not afford the risk and just bought a dpG5 instead. Man was
it worth it.
