Yep, just read that somewhere in my searching today and someone mentioned it recently in another thread.
There was an interesting bit in the section of the Radius Q&A about the Apple Hardware Test always reporting VRAM as bad on any second source Video Card. It also suggested using a different testing utility than Apple's(?) for Video Performance, which is weighted toward functions other than those leading people to have payed more for a High End Video Card than they would have spent for the target Mac.
That's probably the same utility that shows MoBo Video performance besting those same High End Video Cards. MoBo Video never stretched resolutions for 24bit Color and MuscleCards aren't optimized for the tasks the standard utilities run at lower resolutions and lower color depths.
