Some people say that the mining efficiency of 470 is also similar,if we replace the AMD 470, then the whole machine can be cheaper for about 1000 CNY.
Please do make a RX 470 4GB version if you can get it to cost 1000 CNY, that price point would make this an absolute steal. I would order at-least 5, right away.
BTW I would need these shipped to India, and there would be a hefty import duty on top for me, but I'd still want them.
In any case, great job guys, I wish you have made this 6-8 months ago before I put all my money into building rigs.
