Are you still sure Claymore is faster?
he is 100% correct, the new -strap settings in Claymore are the sh*t, i can mine 34.8 MH/s on my GTX 1070 with 105W. On PhoenixMiner it's about 33 MH/s.
It depends on whether you can get the straps to actually work. A lot of people, including myself, have had a hard time getting the straps to run stable.
My rig crashes after about thirty minutes after having wildly fluctuating hashrates using the straps. All nvidia Gtx 1070's and 1060's. So until I figure that out, phoenixminer is faster and more stable.
