A qualitative assessment is just fine. I remembered you being on 64bit. That's a great performance boost in itself. Personally, I found that at least a couple drives in a RAID stripe set speeds things up in a fairly cost-conscious manner. When I switched from IDE to SATA, that gave my system drive a little extra kick as well.
Since getting my rig stable, I haven't tackled renderfarming this year. >From the evidence you provide, it sounds like maybe I should. I have to get Cinelerra to run on my MacBook Pro first, though. I smell some work coming for the Mule! :) cheers! scott _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
