Hi all! Ok, so I'm learning to use Blender, and while I do eventually plan on buying a higher end machine once it gets added to our regular services/client workflow, for the moment it's a training/basic exercise in learning. And we have a number of legacy PPC machines in our office, all of which are working, stable workstations. Here's the full list (I plan to pick 4 for work, 1 for controlling; maybe 5): Powermac G5 2X2.0gHz, 6gb RAM Powermac G4 Sawtooth 2X1.3gHz, 2gb RAM Powermac G4 Sawtooth 450mHz, 1gb RAM Powermac G4 Mystic 2X450mHz, 2gb RAM Powermac G3 b/w, 500mHz G4 upgrade, 1gb RAM ibook G4, 1gHz, 1.13gb RAM ibook G3, 700mHz, 312mb RAM imac 400mHz, 1gb RAM I figure the three G4 towers, the upgraded G4 tower, as the cluster with the G5 as the controller (and worker), or for when the G5 is needed using the G4 ibook as the controller (then maybe using the G5 as part of the cluster when it's not being used?). I've read up on server farms using older machine vs. buying a newer workstation, and I understand the differences in cost and results and the like, but this isn't a high-end environment and I'm basically trying to get some performance out of machines that are otherwise sitting collecting dust while I learn. I plan to use Blender and possibly just Xgrid for admin. Thoughts?
