Current best install for 10.5.8 and GTX285?


I’ve got my gear now and am getting ready to get going with GPU. Finally! But I’m confused by the various posts and driver/installer issues as to what’s the best current way to get going. I’m on OSX 10.5.8 with a GTX285.

This post:
says to install from,
then the 2.3.0 toolkit, then the 2.3.1 driver.

Is this right? Maybe a sticky with current best installation methods would help?
