It is true that nVidia cards are better in OpenGL and that is because of drivers. This is mostly past. ATI drastically increased performances in OpenGL last several months. In some OpenGL games like Q4 now ATI is faster.
In DirectX depend from publishers. Some publishers have contracts with ATI and much more with nVidia.
