* CUDA version only:nVidia GeForce 8xxx and up, at least 256mb of video memory.
* LATEST nVidia-driver with CUDA support.Standard drivers might be a bit older (as CUDA 2.0 is still beta)
* CPU with SSE2 support (P4, Core2Duo, Athlon64, Sempron64, Phenom).
* Recommended 64-bit OS (WinXP 64 or Vista64). 32-bit version is also available.
it is much faster then other crackers, because this cracker is gpu-based ( not cpu ).
this article is a good explanations for the reason, why gpu is in the most cases more
useful in the matter of performance.
