I've come into 2 Power macs, a G4 450 and a G4 450 DP, and was wondering what os I should put on them, and actually which one to hang on to, since they are so close in specs.
I've got some old mac minis, so I don't need another early OSX machine, unless it makes these run better.
So my real question are.
A. Which of the 2 to keep? Does having the second cpu help older games and such?
B. Which OS to put on, OS9 or OSX 10.4?
The DP is undoubtedly the better CPU card for sure. Even though 450MHz is at the low end for a G4, a pair if them greatly helps prevent as much lockout in OS X when doing high computation load tasks (which unfortunately is most things on a 450MHz CPU!).
Another thing to make sure you check before parting with one of them: Are either of them Gigabit Ethernet models, because I'd definitely keep the system with Gigabit over one with 10/100 even if it means swapping the CPU cards (10 mins and a bit of thermal paste).
As for OS, I usually swing gor 10.4.11 on anything sub 1GHz as it's a much smoother experience, just make sure you have plenty of RAM. I like to fit 1GB for letting Tiger stretch it's paws! OS 9.2.2 might also be good in a 'dual boot' setup as it is very fast on any G4 as a rule, but won't make as good use of tge Dual CPUs.
