It's possible to mix AMD and Nvidia cards on the same mobo, but it tends to be temperamental and not really advisable for the noob miner.

I have a dual GTX 1060 3GB rig mining ZEN that delivers about 610 H/s on average and uses a total of 315W at the wall (the entire system). Cards are set for 85% power limit and modestly overclocked to 2000/4150.

If you mine a Cryptonote coin like Monero, Electroneum, etc., then a powerful CPU can easily pull its weight. The Ryzen 5 1600 I have in one desktop does 370 H/s while an older FX-8300 still delivers a respectable 190 H/s; a really ancient Phenom II 955, however, only manages 55 H/s and Windows (7) slows to a crawl.

So a possible setup would be two RX 570 or GTX 1060 plus a decent CPU so you can use a GPU miner program at the same time as a CPU Cryptonote miner (e.g. - Claymore's v3.9).

Totally agree... mix and matching AMD/Nvidia is not trivial as depending on what miners you use it might not be so easy
For instance Claymore's Ethereum mining would work on both Nvidia & AMD however its Cryptonote (XMR/ETN) is only AMD, you need a separate software for Nvidia
I would recommend trying to get 2 AMD RX 580 it's more profitable than the GTX 1060 however not by much (for the past few months atleast)

If you want a decent gaming PC, you'd better have a clear vision of what you're expecting, since that will place constraints on at least one of your cards, your CPU choice, and other components.

1. You can mix AMD and Nvidia GPUs fairly easily on Windows. Most Linux distributions tend to make mixing them much more of a headache, but it is possible.

2. This depends on the exact components selected. Also note that the typical unit for power is watts (joules per second), not w/h.

3. This depends on your goals for the rig as a gaming system. For most users, an i3 or i5 will suffice. Alternatively, you could go with an AMD-based build. (Pay close attention to the chipset if you are thinking about expanding the rig.)


Note that this rig might not pay for itself. Making a mining rig also work effectively for gaming (depending on user expectations for gaming performance) usually requires additional RAM, storage, a more expensive CPU, etc.
This rig only has 2 GPUs, one of which will be mining part-time. You'd be tasking 2 cards with the burden of paying back not only their initial cost, but also that of the rest of the rig. (This is one reason why rigs with more GPUs are favored, as mining with more GPUs and/or more powerful GPUs makes better use of the overhead cost associated with purchasing and powering the rig base {motherboard/CPU/RAM/etc.}, which does not directly contribute to revenue.)

Of course, you might end up with a nicely "discounted" gaming rig.

Hmmm... ok.  You are using Minergate, which means that you are very new to mining.  I suggest you not use that anymore.  The performance of Minergate is pretty poor.  Since you are new, I can suggest you try Nicehash's tool.  It will use better mining software and pay you directly in BTC.  You can then use the BTC to buy the coins you really want.

There are a lot better options out there than Nicehash, but it's easy to get started with.  The problem you are going to run into with Nicehash is that they have a high threshold for payouts right now.  There are some tricks to help... but this will require a bit more knowledge in mining, exchanges, and wallets.

If you are really wanting to take the plunge, then don't use Nicehash or Minergate.  Find a coin that you want to mine... you can use whattomine.com or crypto-coinz.net for some suggestions.  You will need to download the wallet for that coin, create a wallet address, and then use that to mine the coin at a pool.  You can go ahead and start mining as soon as you get the wallet address, you don't have to wait for the wallet to sync.  Now, depending on the coin you choose, it will use a specific algorithm, you will then need mining software to mine that algorithm.  You download a copy of that mining software, setup a batch file with the relevant information to mine to a pool that supports the coin.  Depending on the pool, you may have to set a threshold for payouts, or they may have automatic payout thresholds.

There's a lot... and I mean a lot of knowledge in between those sentences in the last paragraph above.  This will take some time to acquire.  I suggest you start with Nicehash, and spend a couple, or more weeks reading articles, watching youtube videos, and reading the threads here.  Hopefully after those two, three, or four weeks, you will have gotten enough BTC from Nicehash to cash out, and you will be ready to graduate to mining specific coins.

I hope I don't come off as rude, but it's impossible to transfer years of knowledge in a few paragraphs.

Mining software does not provide you with coins.  The pool and wallet are the only things that deal with coins.  You will use mining software to contribute hashrate to a pool.  You will then withdraw coins that the hashrate contributes to from the pool to your own wallet.  There are thousands of coins, and no single wallet that will hold them all.  You are better off using the official wallet for the coin you are mining.  Depending on the pool, you also have the opportunity to mine directly to an exchange's wallet for that coin.  This keeps you from having to run dozens of wallets on your computer.  I say it depends on the pool, as exchanges don't like for you to mine directly to their wallet, but if the pool has a threshold to reach before it automatically pays out, then the "deposits" are not too frequent, and exchanges won't care about this.

If you are using one of the yiimp based pools, then you can keep the coin you are mining instead of having it convert to BTC by using the "c=XXX" parameter on the password of your batch file... where the XXX part is the short code for the coin... like c=GOA for mining and keeping Goacoin... or c=ALTCOM for AltCommunityCoin.

Desigur ca am retras. Se poate retrage prin diferite systeme de procesarea platilor. Bineinteles exista un comision care varianza intre 2-5%. Personal am retras saptamana asta bani.

Banii intra direct pe card convertiti in RON. Desigur exista sisteme care baga banii direct in cont si moneda care o ai la ei pe site. Personal am facut retrageri de pe exchangeuri prin Payeer si Paypal....

De cumparat.. poti cumpara cat ai  bani. O moneda poate fi impartita in parti tare mici.. dar de obicei schimburile au o suma minima....

AirDropurile e gasesti in sectiunea Altcoins. Sunt monezi virtuale care se lanseaza de obicei si pentru a avea o comunitate cei care le lanseaza... ofera gratis o anumita valoare din aceea moneda cu cerinta de ai urmari pe Twitter, etc


eu personal am folosit c-cex.com, novaexchange(dar am inteles ca se inchide sau isi shimba proprietarii... etc). Yobit, Cryptopia, bitrex.

https://coinmarketcap.com/currencies/volume/24-hour/

Aici gasesti o lista de exchangeuri. Iti poti face la cateva cont si poti sa te uiti ce metoda de alimentare au.... si care este comisionul de retragere pentru moneda respectiva....

Practic bagi banii pe card si alimentezi contul lor si apoi poti cumpara moneda. Apoi o transferi in portofelul tau virtual....

Ai putea incepe sa cumperi ethereum si sa fii pe faza la airdropuri.Alta metoda ar fi sa te inscrii la signature campaign si sa postezi.

Acum bitcoinul e foarte scump. Acum a trecut de 6500$. Recomandarea este la fel.. sa cumperi ether... si sa vezi apoi ce si cum.

De asemenea faptul de a participa la AirDropuri te poate ajuta sa mai castigi ceva tokenuri.
