I should maybe post my xbench score with 10.5.2, but it's slightly lower around 123
I tell you what I do find interesting about these scores though
firstly my overclocked 3800 seems to benchmark higher than a lot of more expensive processors
secondly has anyone noticed the scores for DDR400 compared to DDR2 memory?

here are my results :)) poor me

What's your setup Doix?

Processor: AMD Athlon™ 64 3200+(Venice) 2.0 Ghz / MMX, 3DNow!, SSE, SSE2, SSE3, x86-64
Motherboard: MSi Amethyst-M
Graphics: Ati Radeon Xpress 200
Hard Drive: Samsung IDE (160 GB)
Sound card: Realtek AC97 Audio
Memory: 1280 MB DDR Kingston

What can I say get that processor overclocked

i can't :) HP bios... anyway i'm happy with my PC especially with OS X on it :) its much faster than it is with windows... despite what the benchmark says

Yeh I don't think theres much difference unless your compiling code or playing demanding graphics games etc.
Have to agree about improvement over windows, takes my system a third of the time to boot and just gets better from there on.

the biggest difference i noticed is in adobe after effects, in xp (where i have drivers for my card) it takes me about 15 minute to render a 2 minute edited movie, in osx(using callisto, cant say i got qe/ci) it takes 2 minutes :) now thats improvement :D

More Systems can be added to http://mac.kbot.de/leopard-amd-xbench-scores/#more-7

If you like to see yours there, PM me, and I'll include it. :)
