I'm afraid that almost all systems are now GPU limited.

Only multi GPU systems can take advantage from other ecc improvements (if there will be) and from n-k symmetry. I think that a GPU version of ECC library is not very useful at the moment. We need overall to speedup sha256/ripemd160 on GPU.

You are right: Multi-GPU systems are not GPU limited and the client has been tested already on Systems with as many as 16 GPUs. (currently the Amazon p16.xlarge delivers 175 Mkeys/s)

I have already a n-k symmetry prototype running - in fact had this already May, 25th:

The single showstopper to enable n-k symmetry is accounting work that has to be done on the server.

In theory, with n-k symmetry and better hash160 OpenCL code (which I believe is possible - see also https://lbc.cryptoguru.org/crowdfunding), we may see 2x speedups on the same hardware.
