Apple Logic Pro /LogicExpress Discussion

I just barely loaded Logic Studio; I load the Jam Pack and few other things. When I start up 
I get an alert telling me that I am not at the recommended processor speed. I was 
wondering if there's any one out there with the same PowerMac that's having a happy time 
with Logic Studio running on same like machine?

What did you load from the installer
What should i expect when running studio on my computer
What I am I missing while running it on my computer
Any other feedback or tips would be helpful

Thanks in advance,
