[iBook] OSX or not on clamshell G3 366

[Germain]

Hello to the list,

I have a brand new and never installed bought copy of OSX 10.0. Should I
install OSX on my clamshell graphite G3 366, 192 ram, 6 gigs? It's now
running on 9.2. Would OSX slow down every process? Is there enough RAM? Is
it worth installing it anyway? The iBook is mostly used for Word, Explorer,
Entourage and some light Photoshop use? OSX apps I have are: MS Office and
FM Pro 6.

Thanks a million times

Germain
