Well, I'm using 10.4.11 -- so it won't work?
No, it works fine with 10.4.11. It didn't work ONLY with 10.4.3. After
you use PCI Extreme you can check it using Quartz Extreme Check. It
should also show up in System Profiler as "supported". Another easy
way to check is the screensaver Flurry which is smooth and beautiful
if QE works, and slow and painful if it doesn't work.
Is there a gain in speed?
Depends upon what you're using. For non-QE things there is little
change. For QE things the difference is giant. For example, Google
Earth simply won't work without QE.
Is there any advantage at all?
Yes, and some are giant. Scrolling speed of large complex windows is
one giant advantage. Without QE it will scroll jerky and slow; with QE
it will scroll smooth and fast.
I don't want to make my Mac OS X installation unusable by
experimenting too
much. The G3 serves me well at work, so I don't have the time to
reinstall it
all just because I make weird things with it.
In my experience PCI Extreme doesn't ever cause problems that would
require you to reinstall a System, or even not be able to boot. It
either works or it doesn't. If it doesn't, it's more likely that
you've done something wrong, or perhaps your video card doesn't have
up-to-date firmware.
The things to remember:
1) you can't mix non-QE video cards with QE cards. For example, no
Rage & Radeon in the same Mac at the same time. The thing you said
earlier, about BOTH an AGP & PCI together is also wrong, they work
fine together as long as BOTH have QE enabled. If you DON'T use PCI
Extreme to enable the PCI card, you lose the QE on the supported AGP
card also.
2) remember on the B&W & Yikes to keep the video card in the special
video PCI slot which has twice the bandwidth of the other PCI slots.
On a normal PCI slot the best speed you can obtain is the equivalent
of 1/2 AGP, but with the special 66MHz slot you can get 1xAGP speed
which is fine for QE.
3) check that firmware on your video card first, and update before if
necessary.
