Noob question how the hell are people running 3GH rigs? On eth there are 10GH rigs?
Are these people seriously running 100+ 290x cards??
I have 4 cards running and only reaching 90MH :-(
1 rig with 6 R9 290 ---->167 MH
7 old as shit 7870's (5gb ram) gets me 130mhs. I am very happy to put my older gpu's to great use.
You can probably get them off eBay for next to nothing. They also mine vert better than my 280/290x's.
