Umm, I'm next to positive that the NVIDIA and ATI/AMD chips on many (other) Mac machines can easily outperform what Intel has in those CPUs. But I know that NVIDIA is woefully behind on current generation hardware let alone able to provide any kind of support for older gen stuff like what's in my 2009 MBP.

Apple went 100% NVIDIA this year, completely shutting out AMD from every single SKU, and it's one of the reasons they're over a year behind with many of their platform announcements. Lots of NV screw ups and inability to meet quality and quantity standards.

The funny thing about that link Tom, I used to have to explain technical stuff to the two ATI people Anand mentions all the time.
