I already saw your GUI, nice work, keep it up!
I am always open for suggestions of improvement, i actually just started yesterday.
Getting about 170kh/s with the 750TI, tried to overclock it, but over +70 MHz Core Clock the nsgminer throws an error (-5), I am running it now at +70 MHz Core Clock and +350MHz Memory Clock.
I’ll try ccminer aswell, to get an overview of all the miners available.
