The reason for OpenGL is a different one: DX had a very crappy OO implementation till managed DirectX where OpenGL is plain procedural ... which is for scientific usage still the normal way to go (at least as long as C++ holds as standard).
Vanilla: You can already have 10Ghz CPU at Apple (Quad 2,5Ghz G5), so we are really above that.
Even Intel is next to it with their DualCores which only need 2 Cores to get next to the 7Ghz :-)
Beside that he dsaid hardware performance not CPU. And the GPU become by far more powerfull than 1000x because on Amiga you did not have a graphic card by todays meanings at all.
