You tell me!

i got 176 w/o HD in 10.5.4 -----> up to 186 w/o HD in 10.5.5 9f32

Maybe some background indexes were running after installing 10.5.5 like spotlight indexing?

Can you re-run again the 10.5.5 benchmark again please?

Xbench is running round about the same for me but graphics performance is massively improved:



Previous score was around 25,000

I don't think so. You can see there is little difference on Geekbench.
