ok a G5 is sexyier than a g4 but, unless you want to run a ton of RTAS why bother?
a dual FW800 gives you 4 pci slots thats one extra farm card internal drive bays and is supposed to work with this new dual 1.8 daughter card (I agree with the above caution about prossesor upgrades in general but mix has been upgrade friendly in general)
The thing about TDM is that the computing power has no effect on DSP its all in the cards.
I would rather have a g4 400 an expansion chassie Full of DSP than spend the money on a G5 so I could run tons of RTAS.
The only really good thing about this is giveing the finger to digi who said it couldn't be done! and I would rather someone would come up with a stable way of running mix on os10.4 so we could try some of those SSL plugins!
