at home by tests i am using latest optimized app from cruncher page and i have 8500GT only ....
remember , for now aren't in GPU code optimizations (shared mem usage ,memory coalescent access by read/write, optimal thread/block scheduling against core, ). used is only partial loop unroll ...

last weekend i have downloaded GUI profiler for CUDA. It has showed many interesting things .... i will write more later - it would bigger ...
