I suppose what i should be asking is should i swap my 4x1060 getting 91mh at 75w each for 2x1070 8gb running 105w each getting approx 64mh?
Zer0k, I havent bought a case yet but planning to get the Corsair Carbide 240 seeing as its pretty compact.
Looks like that case can accept big ATX PSU's so you're good there and can easily run an 850W unit or even bigger
It really depends on your own power costs, but I would swap to a 2 x 1070 rig and mine SIGT or whatever else is most profitable
2 x GTX 1070 mining ETH @ ~64Mh/s = $3.76 / day
2 x GTX 1070 mining SIGT @ ~60Mh/s = $7.35 / day
Then if you really want ETH to hold long term or any other coin, just sell your SIGT and buy the coins you want on an exchange like cryptopia
