    750000! can be done well under a second with Mathematica 6.0 single-threaded on any i7.

    Yet it takes 1+ minutes using CUDA?



    *Sorry for being off topic.
    Have you got mathematica? Can you show us the result? We already know there are insanely fast algorithms and approximations that can be used http://www.luschny.de/math/factorial/Benchmark.html .... but we also know there are many algorithms for calculation Pi to 1million places.. all with diff times.
