Hey !
Thanks a lot for all these answers ! Really appreciate it.
I'm not sure I should spend more money (getting 1070Ti, for example) since it's my first rig : do you know if the gap between the 1060 and the 1070 (or even the TI) make a real difference ?
(for example, MSI GeForce GTX 1070 Ti AERO 8G is 469€ where I live, which would make the rig quite expansive (around 2800€ just for the GPUs) and the GTX 1060 is twice cheaper (around 220€/GPU)).
Cheers,
So I make a draft calculations for your references, you should edit to fit your plan
(I convert all to usd):
#1: Rig 6x1060
- Total hashrate for VTC: 114 Mh/s
- Total PCs' cost: 250$*6(GPUs) + 140$ (850W PSU) + 110$ (MB) + 125$ (RAM+CPU) + 75$ (risers+frame+peripherals) = 1950$
- Power cost (my cost): (750W*24*30)*0.1$/KWh = 54$
=> hashrate/cost = 114/(1950+54) = 0.0569
#2: Rig 6x1070
- Total hashrate for VTC: 195 Mh/s
- Total PCs' cost: 495$*6(GPUs) + 240$ (Super Flower 1300W PSU) + 110$ (MB) + 125$ (RAM+CPU) + 75$ (risers+frame+peripherals) = 3520$
- Power cost (my cost): (1010W*24*30)*0.1$/KWh = 73$
=> hashrate/cost = 195/(3520+73) = 0.0543
So I'm mining with 1070 cards, just because it could get high hashrate on most of algorithms.
