Thank you.
I now remember why I had kept the 9200 and sold all the others.
I planned a combination of a 9800 + 9200
9800 for OS X and Core Image (but no hardware acceleration, so no OpenGL under OS 9)
9200 with no Core Image but HW acceleration under OS 9
The Geforce4Ti 4600 would have HW acceleration under OS 9, but no Core Image (if I am correct),
but since it is AGP and the 9800 is faster I would have to decide between 1 card and superior OS 9 gaming, but no Core Image under OS X OR 2x cards and Core Image (9800) plus HW acceleration (9200).
Interesting, these benchmarks you linked to, they see the Geforce 4MX second to Geforce4Ti and the 8500 behind both, (well except for Apple Works scrolling test :-) were the 8500 is superior to the 4MX).
I always thought that the 8500/9000 is a better card than the 4MX. (Also see the benchmarks and the 3MX). Here
http://www.jcsenterprises.com/Japamacs_Page/Blog/8923D90A-7AD8-41F1-BD1A-FEA5E1780B95.html the 4MX is behind the 3MX, the 3MX behind the 8500/9000/9200 and those are of course as expected behind the 4Ti. (the 9800 is talked about on the next page which focuses on OS X).
But anyhow, it is hard to say, what these numbers mean in real life. I have a sceptical feeling towards benchmarks in general. I'd say, if you do not notice the difference in real life, well... then what. On the other hand it always gives a good feeling to have some power left for the rare case you do not foresee, but may come some day.
When I think about it, I should make one Mac a sole OS 9 gaming machine
and keep things separted. Then again I think of OS 7 games. OK, I could do that on a sole X machine in emulation or buy a Macintosh SE, which I always wanted to have, but they go so pricey here. and then again all the room that it takes...
I also more like it as small and compact as possible. Sorry, for going off topic.
