(noob)Question, I started using winminer yesterday when i found out how easy it is to mine crypto currency nowadays due to the hack of the other platform. 

So I use 2 GPU's in WinMiner, a old 750gtx (which normally functions as a physxcard) and a 970gtx, WinMiner shows the 750 as doing 260h/s but the 970 only 58 h/s both mining ZEN, i guess this is just a graphical bug and the values should be reversed or are these values incorrect and can i better take out the 750 gtx?
