My CPUs are reporting really low Hs with the new algo, my i7 2nd gen went to 86Hs from 256Hs and my FX 8320 @4.5Ghz is reporting 180Hs from 430hs, on the other side the GPUs are losing a small %.
It's because of 4 Mb buffer instead of 2 Mb, number of threads should be decreased 2 times. Welcome to the GPU mining era!
