At the current profit I would wait, when the new generation will arrive usually prices from the previous generation go down so either you can buy the new and more efficient hardware or you can buy the hardware from this generation at a better price.

I don`t know if you have mining experience already, because if the answer is no, I would suggest then to buy some cards now to get some experience, setup one rig, test with different miners, different pools, different oc settings, etc. . .

At the moment, the prices for cards are very high, and fell quite a bit. And the income from mining fell 2-2.5 times. Therefore, it is not profitable to buy cards now. Either wait for a drop in prices for those cards that are, or wait for a new arrival. And already 1060-6 cards in general there is no sense to take, except that mine etherium on them, which is not profitable at all.

If you can get a screaming deal on 1060's why not?  But with 1060's still at close to the price of what 1070's should be.......  Like others have said if in it for the money its trouble right now.  Cost of equipment versus what you will be pulling in with drop in crypto prices.

well it seems for the 6GB cards you want Micron RAM
for the 3GB cards you want Samsung RAM.

I had an ASUS 3GB card with samsung mem, that ran 25MH, it failed after 6 weeks, and i just got the RMA replacement, also with Samsung mem and it performs the same.

I have 5 Micron cards in 6GB, 1 ASUS and 4 EVGA, the ASUS card will do 22.5-23MH, and the EVGA cards do 24-24.5MH.

Hynix on a 6GB card seems to such universally (20-21MH)
Samsung on a 6GB card seems a crap shoot, the one card i had only did 21 with a +1000 OC on the ram. pathetic.

If you have a good price (i.e., $300 or less/card, hopefully a lot less), then yes. Over $300 I'd just wait, cards are dropping again and 1060s should be in the $250-300 range (or at least all mine were).

Etherium:

1. Hynix memory - 19-20.66 Mhs @~>70W
2. Micron - 23-24 Mhs @~70W
3. Samsung - 24-25 Mhs @~70W

not guaranteed. i had a samsung mem 6GB card that would barely do 21MH with mem speeds cranked +1000MHz.

my 3GB samsung card does 25MH though.

I agree, sometimes bad ones happen. Bios reflash could fix that, too bad they are all locked.

considering i can only get 18,5 mh/s out of my GTX 1060 6gb hynix memory, i would say you are very lucky to get 8 of them to run 23mh/s
