I have the option to get an old  PCI 604 Mac that is upgradable via PCI
Card (Sonnet) to G4 450 MHZ 1Mb cache...

The mac is $100, the card will be $250 plus I will need some RAM. Downside
is that the mac is SCSI based, not IDE (cheap).

Wondering how fast OSX will run on the G4 at this speed? Tolerable?

I am assuming a 450 G4 will be faster than a higher clocked G3 (like a 700)??

Wondering if this is a good route to go ( have to be via charge card
(stupid, just got paid off)) to get to X.

I can use Sonnet's X installer, or XPostFacto to install, but Sonnet's
requires OS 9.1 which I don't have.

I have OSX 10.2 and 9.2 install CD's
