I checked mine and this does indeed seem true. Mine are running at 190w at the wall with a 190mhz OC. Not as bad as yours, but still not as good as my other cards. Also 40% TDP they're pulling 85w and around 10000MH on quark.
are you really getting 10,000 MH on quark out of a 970 ?? or did I read this wrong..
I only get 10,000 KH per card how are you getting double ??
GIMMIE !!
