I think power delivery issues are more common in the 470 but I dont know for sure. I would get the 480.
So 480 4 gb is the best one at the moment?
I would like to start with 6 cards guys and update you with some pictures when I have them build in a rig. My electricity is relatively cheap so hopefully will get at least 7% monthly return, do you think 7% is possible with rig 6 cards 480?
Thanks!
