Topic: Best ROI on USD for new and current mining setup (Read 1370 times)

1070 cost less and quicker ROI but yeah I'd go 1080 over AMD at this point with the card shortages of AMD

Many people set out mining with a small start rig like yours, set their eyes on the next stage up and by the time that the funds are there for that next step up, the next step that they aimed for is way behind the times.

First off, do not ask the members here for financial help.  With a brand new account, they will assume that you are scamming and you will lose the attention and the tendril of trust that you have at the moment.  Secondly, read, read, read and read some more.  That is not that much to get started for mining and you need to ensure that by the time that you get rolling a little bit that you can afford to upgrade.

Or I could just go for a full 1080 Ti rig

Thank you for your incredibly descriptive reply.

So a decent mining rig to complete my current computer would have:
5 x RX 580 8GB 256bit 300 h/s on Claymore ZCash 1,500 h/s (1.200W running total) (USD 1.750)
1 x R9 390x 8GB 512bit 400 h/s on Claymore ZCash 400 h/s (1.510W running total) (USD 0.0)
1 x EVGA SuperNOVA 1600 T2 80+ TITANIUM (USD 410.00)

Running Totals (1st rig)
USD 2.160
Watts 1.510
H/S 1.900 h/s WhatToMine = $500/month @ 10.75c/kWh (4 month break even)

A decent new mining rig would have:
6 x RX 580 8GB 256bit 300 h/s on Claymore ZCash 1,800 h/s (1.440W running total) (USD 2.100)
1 x EVGA SuperNOVA 1600 T2 80+ TITANIUM (USD 410.00)
1 x Recommended MB + Processor + RAM + SSD? (USD 295.00)

Running Totals (1st + 2nd rig)
USD 4.965
Watts 3.200
H/S 3.700 h/s WhatToMine = $973/month @ 10.75c/kWh (6 month break even)

1- Any recommendations on what MB/Processor/RAM setup to use for 2nd rig?
2- What about PCI Risers? Which should I use?
3- Can I just plug all this into a wall outlet? Do I need to have any special considerations? Do I need to ask for any special permit in the USA to start mining at this level?

Thanks!

1.  It looks like the consumer version of Vega will release around August 3, but keep in mind what past AMD flagship releases have been like;  there's almost no way that you'll be able to buy 5 of them on Day 1, or even in the 1st month, tbh.  No one really knows what Vega will be like as far as its mining capabilities are concerned;  it will probably be awesome, but there's no telling what the price will be like, and if it is an incredible miner, expect them to be sold out constantly for at least 6 months, with prices at a premium above msrp when they are available.
The biggest consideration here, however, is why you are mining;  if you're interested in making profit, then everyday you wait is a day that you're LOSING money.  Generally, the best way to go if you're looking to mine with AMD is to buy all the RX 480's you can and just GET STARTED.  Mining ETH, an RX 480 @ $250 should pay for itself BEFORE the new Vega cards even come out!  You can use the profits from your RX 480's to BUY the Vega cards if you want (^_^)!
A lot of people have tested the RX 480 vs RX 580 and found that the hashrate is nearly the same, but that the 580 uses more electricity for some reason.  If the RX 480's are unavailable or are just being priced too high for some reason, RX 580's are a good substitute, and will also pay for themselves BEFORE Vega even comes out.

If you want to go high-end, however, you can always consider Nvidia;  I take absolutely no sides on the Green v Red debates, I own cards from both companies right now.  AMD gets much better ROI on ETH, but right now I'm getting more than a LOT more profit/day from Nvidia (1070/1080).  Here's an example of what kind of performance I'm getting from my GTX 1080's using CCminer 2.0:  https://whattomine.com/coins?utf8=%E2%9C%93ð=true&factor%5Beth_hr%5D=28.5&factor%5Beth_p%5D=105.0&grof=true&factor%5Bgro_hr%5D=92.0&factor%5Bgro_p%5D=130.0&x11gf=true&factor%5Bx11g_hr%5D=12.5&factor%5Bx11g_p%5D=120.0&cn=true&factor%5Bcn_hr%5D=500.0&factor%5Bcn_p%5D=100.0&eq=true&factor%5Beq_hr%5D=465.0&factor%5Beq_p%5D=120.0&lre=true&factor%5Blrev2_hr%5D=48500.0&factor%5Blrev2_p%5D=130.0&ns=true&factor%5Bns_hr%5D=1050.0&factor%5Bns_p%5D=155.0&lbry=true&factor%5Blbry_hr%5D=387.0&factor%5Blbry_p%5D=120.0&bk2bf=true&factor%5Bbk2b_hr%5D=1600.0&factor%5Bbk2b_p%5D=120.0&bk14=true&factor%5Bbk14_hr%5D=2500.0&factor%5Bbk14_p%5D=125.0&pas=true&factor%5Bpas_hr%5D=940.0&factor%5Bpas_p%5D=120.0&bkv=true&factor%5Bbkv_hr%5D=0.0&factor%5Bbkv_p%5D=0.0&factor%5Bcost%5D=0.1&sort=Profitability24&volume=0&revenue=24h&factor%5Bexchanges%5D%5B%5D=&factor%5Bexchanges%5D%5B%5D=bittrex&factor%5Bexchanges%5D%5B%5D=poloniex&dataset=Main&commit=Calculate&adapt_q_280x=3&adapt_q_380=0&adapt_q_fury=2&adapt_q_470=3&adapt_q_480=2&adapt_q_750Ti=0&adapt_q_10606=0&adapt_q_1070=1

The estimates that whattomine.com uses for the 1070 are almost 1/2 of what I'm getting for Groestl, and about 30-50% lower on LBRY, or Lyra2Rev2.  But if sticking w/ AMD, which is better ROI for Ethereum specifically (a currency that's going through the roof lately), Just grab some 470/480/570/580's and get started, definitely do not wait for Vega!  You can always sell those cards later to buy Vega, or just put together a new, all Vega system and SCALE UP!

2.  It still looks like Ethereum (ETH) is the way to go w/ AMD.  Ethereum mining is getting harder, of course, and they're planning at some indeterminate date in the future to switch to a PoS system instead of PoW, but if you're willing to HODL! for just a bit longer, Ethereum prices just seem to be going up & up, and while we all thought that the cries of "ETH is the next $1,000 currency" seemed like hyperbole a few weeks ago, it doesn't seem like an exaggeration anymore...
ZCash is by no means a bad currency, however.  You could always just mine both of them at the same time, if you want to hedge your bets.

3.  Probably.  Nobody knows yet, but...  I don't see why not right now.

4.  For AMD, yes.  Especially with a card that's been out for a while, like the 280x or 390x, people have had plenty of time to get the BIOS mods fixed, and then fixed again.  For Nvidia cards, it gets a bit more sketchy, especially with newer cards;  on the 10xx series, BIOS mods have to be "Signed", which makes the whole process slower and more difficult, which is why you don't see many mods for it.
If BIOS Mods make you nervous, though, you can get most of the performance you would get out of it from a simple overclock/underclock procedure in Afterburner.  BIOS mods are really for squeezing that last $0.05/day out of each cards, you won't see "10x THE PERFORMANCE PER CARD!!!" from it or anything.

Trying to start a small scale mining operation.

Currently have:
Gaming 3 Z170 Gigabyte
i7 6700k
16GB DDR4 3Ghz
Sapphire 390x running @ 400h/s with Claymore Equihash for ZCash mining
Corsair 750W 80+ Bronze

I will be removing all this from inside my desktop and installing it on a "mining rack" (aka: kitchen shelf) and upscaling the whole thing to start doing some more serious mining

Questions:
1- Should I go for Vega once it releases? What's the release date?
2- Is AMD ZCash mining the highest ROI today?
3- Will I be able to stick 5 Vegas and 1 390x on the Z170 with the F20 BIOS update?
4- Never modded any GPU BIOS, is it worth the risk? What efficiency change are we talking about?

Thanks for your time to read and help!
