G5 too slow

Hi, my G5 used to render pretty fast, now it renders much slower. Is it too full, too much garbage? should I trash something else?
G5, 10.5. dual 2g, 2.5gram, one internal hd where i have projects-applications (100g, about 35 available), a second internal hd with media (150g, about 40 available). Does disk warrior help?
Thanks!

I recommend running a cache cleaning script at least once a month. I use Main Menu (all tasks) and that, along with repairing permissions seems to keep my Macs running smooth.

Yeah, Repair Permissions at least once a month is good preventive measure. When all else fails, resetting the PRAM helps.

Thank you guys, i repair permissions from time to time, how do i clean cahe and/or reset PRAM?

I'm looking too.

Use to use MacJanitor and CacheOut X, but they have not been updated for Leopard.

Does anyone like TechTools Pro for Mac maintenance?
