running -t 0,1,1 does bump me up to 5900c/m on one instance, or if i go with two instances, 3400c/m and 2500c/m
however, cpu load never went up above 15% on the other one, running on a qx9650 @ 4.0ghz
why such high variance on two cards running exactly the same clocks?
even if just running cards by themself, one at a time, -t 0,0 gets 800c/m, -t 1,1 gets 3400c/m
