Another way to speed up performance on your iMac 266 Megahurts is to download TinkerTool from http://www.versiontracker.com/macosx/. With TinkerTool, you can turn-off antialiased text. You can also reduce your monitor settings from millions to thousands. I tried this and it sped up things significantly on my Mac, but I eventually set everything back to the default settings.
