I have two Nvidia cards 970gtx running.
They give a hashrate of 37MH on a PCI expres port 2.0.
On a good day they run 50MH at max.
I dont know how much it does on 3.0 but i think its not much more!
The GTX 970 that someone locate me give me each between 16 and 20 MH/s. You get 18,5 per crad, so this is really good

!
By the way, I came back to Expanse after the Ethereum little price dump that make my daily profit a bit low. I'd like to know how to recover the 1,5 EXP that Franko gave me when the GUI wallet was released, can someone help me to do so

?
