Performance of NVIDIA Geforce 8600

CudaMemcpyHostToDev=18 microseconds
CudaMemcpyDevToHost=23 microseconds

Performance of NVIDIA GTX 580

CudaMemcpyHostToDev=6 microseconds
CudaMemcpyDevToHost=8 microseconds

As we can see that NVIDIA new GPGPU cards like GTX series with FERMI memory architecture is much faster by itself than old NVIDIA crds like Geforce series.
