I have the option to get 1070 Founders Edition for around 400-450€ while 580s are sold out everywhere. Does someone know if 1070 is equally good or better in terms of price/performance. Looking to build 6xGPU rig fow now.
Also, what about other coins (not ETH) and dual mining? Any cons here in regards to 1070 vs 580?
nVidia fanboys will tell you that nVidia is better, but one should always consider the facts:
-Yes nVidia might be better at Zcash, but for the most popular coins afaik, it's more or less the same. Modding AMD polaris cards is a breeze
-nVidia are supposedly less power hungry. All I know is you can undervolt an AMD pretty hard to the point where I don't think it makes much of a difference
-nVidia will supposedly have better resell value. This might be true, but with the amount of people buying these cards, once everyone starts offloading them on the secondary market, their resell price will inevitably fall
-nVidia are more or less available while it is indeed hard to get 570/580s unless you preorder
I'll give you my honest opinion: I don't think nVidia cards have a price/performance ratio that is so great that they are a better option over AMD and I would absolutely not buy a GPU for that price. 400-450€ is about twice the price for an RX when they are available. This simply means you'll need to account for a longer ROI time. The question is: would you rather wait another month (if not more) to get a cheaper AMD card or get mining now with an expensive card. If 1070s were around 250-300 I might consider it.
I think many miners are in FOMO and will tell themselves they'd rather fork out 2000-3000€ for an nVidia rig than have nothing. I would say, don't waste your money in hardware atm, go to an exchange and buy some coins. ETH's price is falling again, might be a good time to get some.
