The G5 Power Mac will work harder and slower with10.5.8. I use 10.4.11 and 
10.5.8 on my G5 Power Mac Dual 2.7.The removal of dust will make a difference. 
What CPU temps do you get between the systems? Also ASD 2.5.7 will check a lot 
more than the AHT on the start up disk. I would basically disassemble it and 
give a good cleaning with compressed air (not the little cans) I use a unit 
like this to do the job.
