hi. right now i have a powermac g4 dual core 1.25ghz and im buying a used G5 2.3ghz dual core. i was wondering if i could just swap the airport extreme card out of the g4 and put it into the g5 or are they not compatible? ive read the how-to threads but i cant seem to find a straight ans on this one. on one site apple says the extreme will fit into a g5 but on another site they say it wont work work with the g5 dual core. any help would be appreciated. thanks.
