If you read the documentation on 10.5.6 Update, one improvement reported in the Apple Support document is "general improvements to gaming performance." (http://support.apple.com/kb/HT3194)
I benchmarked five games on both a Mac Pro 3.2 (GeForce 8800 GT and Radeon 3870) and MacBook Pro 2.8. Those tested include CoD4, ET:QW, Halo UB, Prey, and WoW.
The only performance improvement I measured was with CoD4 on the MacBook Pro -- 15% faster.
I'd love to hear if any of you have measured specific improvements in average frame rates of a particular game I did not test.
