For 3D Application performance, NV25 (Quadro 4 900XGL) still beats* R300 (Radon 9700).
That's no surprise when running OpenGL software. The review was comparing how cards optimized for DirectX stack up against the OpenGL optimized Quadro 4 running OpenGL apps. ATi's equivalent to the Quadro 4 is the FireGL X1 and not the 9700.
However, the fact still remains that the R300 is one superfast DirectX 9 card with decent OpenGL performance. Until the NV30 is released, ATi's 9700 is the DirectX king.
But who cares about DirectX anyway... :-D
