6x1070 rig - TDP 112w (60% for me) - OC +185/-500
Tpruvot ccminer 1.8.4
1745 MH/s
LBRY sp-mod #5
~1770 MH/s (+1.5%)
so basically the boost get eaten up by the fee

Also seeing something weird when on yiimp, miner crash each time the pool ask stats.
I got pretty similar results, with ccminer (1x1080 and 2x1070) I made about 958 MH/s and with sp-mod #5 about 977 MH/s so it is about 1.20% faster
