Can anyone tell me what kind of hash power you are getting on a Sapphire R9 290 Tri-x? Also what is the power consumption when mining DMD's? I am considering a few of those to go along with my 750 ti's.
Thanks.
750ti are superior in mining groestl algo performace per watt
i would consider a amd290 only if u plan use that GPU for games too
for pure mining invest in lot pci slots on multiple mainboards and fill em with 750ti
compare
20mhash @200watt amd290 = 10mhash per 100watt
8mhash @50watt gtx750ti = 16mhash per 100watt
thats 60% advantage in hash per watt performance for 750ti
