Why exactly do you think that a GFCI would provide additional protection against voltage problems? All a GFCI does it look at the current going in to a device, and the current leaving, and if the two are different by more then a specific amount (I belive this is usually 0.005 Amps) then they trip. They are designed to detect shorts, not to detect power spikes, so they won't provide as much protection against things like power spikes as compared to a good surge protector, or even your UPS.
