...there is a test somewhere to check if your sawtooth can handle dual processors. i think it is downloadable even at many websites selling CPU-upgrades.
in fact, the 350 AGP model might work well, cos it was actually the second generation sawtooth board. (apart from that pci/agp-business, the very first basic models were 400MHz, but got downclocked later, remember?)
try out sonnettech or OWC or the like for that little application...
Actually, the 350 was a first generation Sawtooth, though there was also a 350 PCI (Yikes) machine.
Sawtooth rev2 was actually the Gigabit Ethernet (AKA Mystic), and did not offer a 350mhz configuration; single 400 was the baseline, and the other two offerings were dualies.
I realize some refer to it as a Sawtooth 2, but for sake of simplification and separation (there are many differences between the two, to include CPU and GPU upgrades) most sites with Mac listings will differentiate between the two as Sawtooth and Gigabit Ethernet, respectively.
