Leopard ...

[samsc]

Careful with Leopard and x1900, they don´t go along well. My system started freezing from out of nowhere. Took some time to figure out why, as I´d put in some more RAM etc. But hopefully the machine is cured with clean fans and a clean 10.4...

some x1900 have heat issues- they have been half documented-
i had a demo machine from apple at LDI trade show which had screen corruption.
I managed to switch to tiger- and problem remained. so its not OS related.

x1900 is a good video card- the 7300 is really lame.

One theory I came across was that Leo generally uses the GPU more than Tiger, so that it will become hotter. I can only speak for myself, but my x1900 worked like a charm for a year with Tiger, and crashed repeatedly with Leopard. Every morning the machine would have frozen from just being idle. And Quartz Composer gave me hourly freezes when running a bit hard.

its not nice to go from rather stable 10.4.11 to the instability and poor performance of 10.5.1-

drives me crazy - every couple of years - the entire system gets broken - and we have to start from scratch-
its nonsense.

i get the feeling there are significant numbers of bugs not resolved in 10.5

for me though the main problem is terrible performance -
