The 140 FPS at 800x600 resolution is what was reported in 2010 by visitors of a show where the new R200 3D drivers were presented in action. Just click on the text of my previous posting and you should know more.

The 60 FPS result for 800x600 on Mac mini reported by koszer (as well as the 70 FPS reported by Cim on Mac mini in the other thread) doesn't make this appear likely.
