In OSX Snow Leopard / Godalming UK     i have a power mac g4
quicksilver with a upgraded 1.2 ghz cpu but i want to upgrade it
to a duel core/duel cpu but ones like the sonnet cards are
expensive (can bee £300+) and i was wondering if a duel 1 ghz
out of another g4 would be faster and if it would work   2.
macrumors 65816      Jul 4, 2007     Yes, unlike a G4 MDD, you
can indeed do this on a G4 Quicksilver.      After installing
the new processor, reset the CUDA switch (after taking the
battery out and unplug computer from wall socket) before
powering up the first time or you'll just get a grey screen and
a message telling you to restart.      NB. This advice is from
what I've read elsewhere and not based on my own experience.
