partially upgrade, partially repair. everyone knows about my fried wallstreet and my conquest to find a new processor, and all i can find right now is the sonnet creschendo g3 card. first off, does this need software to install? i can't exactly do that without a working processor in the computer. and for anyone who has it, is it any good? lastly, what else is there that i haven't found that might be more stable or a better value? i don't care about my powerbook's existing bottlenecks. i want to keep mine running for the sake of saying i have a ten year old powerbook that still runs well.
