I'm mining with ccminer skunk mod sp1

At intensity 25 with 2x1070gtx I'm getting 55.76 Mhs - that's 27.88Mhs per 1070
At intensity 22 with 3x1060gtx I'm getting 46.24 Mhs, that's 15.41Mhs per 1060

I can probably still increase intensity with 1060, not sure if it's worth it though. 1060 crashes at intensity 25.

Is sp3/4 better than sp1? By how much?
