GeForce 400 Series - Wikipedia, the free encyclopediawikipedia said:OpenGL Problems
It has been reported by users as well as developers that nVidia 400-series cards have severe performance problems with 3D content-creation applications such as Autodesk Maya and 3ds Max, Blender, Rhinoceros 3D—as well as some OpenGL games—to the extent that video cards two generations older routinely outperform 400-series in such applications and games. The problem, which affects any OpenGL application using textures, involves accessing framebuffer contents or storing data on the GPU. So far, one customer using an OpenGL based application got a response from nVidia support indicating that the behavior is expected in the GeForce 400 line of cards, and no software update is available to improve the performance of the hardware. The problem can be worked around with a hack by using a CUDA memory copy to access the buffer object.

these problems still exist in 500 series and still not fixed.
