GTL is like inter-FSB communication votlage...voltage for core-core communication. AS the FSB is the bus used for this communication, CPU PLL has a similar effect as well, however you'll find that GTL tweaking only really shows signifigant gains for quadcores, and not duals, as the source for each of the operation's votlages(GTL, CPU PLL) are related, but not the same.

GTL is liek the "low" setting to "HIGH" setting voltages for communication, "low" being like a "0", and "HIGH" being a "1". these ride within the FSB voltage, but FSB is bus for cpu-chipset, and each provides it's own power source for out-bound communication, so each must be tweaked individually, as each will have a differing load on them, based on what work is being done. The GTL voltage will drop as it gets to each core, a little bit, and when you increase speeds, this drop is larger, so we adjust GTL to compensate for this. A board with lots of expansion cards and 4 DIMMs is more likely to need chipset FSB volts than CPU FSB volts, due to the load on the chipset, while on a board with jsut a vidcard and two DIMMs, it's not going to be as important.

SAme for the cpu..quad is more work than dual, and high FSB is more work as well...so hopefully by now you kinda understand what's going on with these settings.
