Here's a summary of the empirically determined optimal -m values for various GPUs on this sieve:
Model              Optimal -m value
nVidia GTX 460      2048
If you have a GPU that's not in this list, please experiment with various values (2048 is probably a good starting point) and let us know what works best! Note that all -m values must be multiples of 128.
