Re: My 1 card now a 2 card rig for Ethereum. One day of mining so far. Photos thoughts.

i can find everything at around 430 euro on amazon, risers on ebay

Amazon gives me a good price for this set up (I have 850W power supply)

Should I start from loading with 2 R9 390 and later add 2 more?

Is this card good?

XFX DOUBLE DISSIPATION R9 390 1015MHZ XXX OC 8GB DDR5 DISPLAYPORT HDMI DUAL DVI
$320

seems that the 390 is the best, but polaris is coming not sure if it is wise enough to buy gpu now

Polaris according to my country's local agent, their Hong Kong office mentioned Q3/2016 launch... so we may be looking at Sept...
On the other hand, those Nanos are also good because of its superb undervolting capabilities.... I am getting a few and would be doing Ellovp/Heliox's ROM mod.

With his mod, the R9s can do the following: 134 Mh/s @ 2.25A, 495watt (6 Cards) stock settings rom OR 185 Mh/s @ 4.8A, 1050 watt (6 Cards) 1020 Core, 300 Mem
Mining ETH is about racing against time (before POS) so you will lose a couple of mullahs if you wait for Sept. My 2 cents.
