Wouldn't that be sort of pointless to put 2 processors that consume massive amounts of data on a 133MHz bus?
It's silly to hobble 1 processor with a 1GHz FSB behind a 133MHz wall, but two of them. 😱
That's almost as silly as Mr. Leadfoot taking a race spec prototype Twin Turbo Porsche with a 2 gallon fuel cell on a cross country road trip.
Considering the cost and performance of that type of upgrade, keeping the machine and buying a 1.6GHz G5 would be a better alternative.
