Hi Michael,

thanks for your efforts on the Intel graphics, but actually there is probably a little misunderstanding. There are quite a few chips with a 3000 in the name. Here is a short chronological list (from http://en.wikipedia.org/wiki/GMA_X3100 and http://en.wikipedia.org/wiki/Intel_HD_Graphics ):

Graphic chips on motherboard:
Intel GMA 950 (MacBook 2006 - mid 2007) Luis's MacBook
Intel GMA 3000
Intel GMA X3000
Intel GMA X3100 (MacBook late 2007 - late 2008) My MacBook
Intel GMA X3500

Graphic chips on CPU chip (Sandybridge):
Intel HD Graphics 2000
Intel HD Graphics 3000 (MacBook Pro 13") Your MacBook Pro

Hope that helps a bit...
