I have a Mac Pro, early 2008 model with a Quad Core Intel Xeon CPU.
Since 2008, I have installed the graphics card upgrade kit that Apple started selling around mid 2010, the Nvidia GTX285.
I'm curious: what is special about a "Mac" graphics card that standard graphics cards don't have?
Since the transition to Intel CPUs, aren't the internal components of a Mac even closer to those of a PC?
Would a standard graphics card work in a Mac Pro, and if not, why?
