Hello… I am new to the altcoin scene and am trying to ascertain if I can make a reasonable profit by building a decent GPU rig. I have been researching components and plan on posting my proposed set-up here in detail before pulling the trigger, as I would like to get opinions from experts before putting down that kind of money.
But, before posting that detailed systems mockup, I wanted to see if there was any way of obtaining hash rate estimates for a handful of GPUs that I have been looking at. I have found what appears to be a good profitability calculator at coinwarez but I only know 2 of the 3 required pieces (watt usage & electricity rates) and have not been able to find a good source for expected hash rates.
Before listing the GPUs though, I wanted to mention that I plan on using MinerGate… probably on a Windows 10 build… and at least for now, mine primarily Monero & Ether. I know that there are other alternative miners but I they seem a bit too technical for me to easily use. I have been running MinerGate for over a week just on my 3 PCs and like the easy to use interface. However, if there is a dramatic difference in productivity, I would be open to considering alternate miners.
CPU: my current desktop has an old 2nd gen Intel i7-2600k processor. When I mine Monero with 7 or 8 cores on this machine, I usually pull about 115 H/s. Note that this machine does NOT have a qualified GPU in it, so my results are solely from that old processor. This is right in line with the benchmarks below, but this is obviously a very old list so doesn’t have any of the more recent hardware.
https://docs.google.com/spreadsheets/d/t_usoLpWsHq7K6-PeYXigCw/htmlview#When I try to mine Ether on this PC, the results are abysmal… most likely because I believe that mining either at decent rates is much more GPU-dependant than Monero.
I can get Intel processors at ~50% off, so I was originally looking at am i7-6800 for about $220 but then I realized that would require an 1151 socket as opposed to the more common 1150, so I may opt for the i7-5820K for about $180 instead. The benchmarks don’t seem to show significant difference between these 2, so thinking saving $40 here and another $40 on a cheaper MoBo may be the way to go.
So, the question here is, approximately what hash rate could I expect from the i7-5820K (or similar)?
GPUs: So, I have primarily been looking at are of the RX470 variety…
MSI 8GB @ $240

http://www.newegg.com/Product/Product.aspx?Item=N82E16814125896&cm_re=radeon_470-_-14-125-896-_-ProductThese all seem to be similar in specs but seems like the 8GB may provide a bit of extra processing power… not real sure though. But they all seem to pull 110W.
Can anyone provide estimated hash rates for these for mining both Monero & Ether? Even if you are not using MinerGate, any actual user data would be helpful at this point.
Finally, I also would consider other GPUs if they have a better power-wattage-price ratio. To that end, I saw these recommended somewhere:
EVGA GeForce GTX 750 Ti 2GB 128-Bit GDDR5 @ $120
http://www.newegg.com/Product/Product.aspx?Item=N82E16814487025#closeThese are half the price and half the GB, but will they also only produce approximately half the hash rate?
Any hash rate data for the GPUs I mentioned above (in relation to XMR or ETH/ETC), or any other highly recommended GPUs would be greatly appreciated! Also, I assume these rates would be scalable… meaning that if a single GPU produces a XMR hash rate of 600 H/s, then 2 would produce 1200 and 3 would produce 1800?
My intention is to get a MoBo that supports 5-6 GPUs, but only buy 2-3 at first to make sure it is profitable once up and running. If it is, then I would possibly add another 2-3 GPUs to maximize that profit. I do realize that returns will diminish at some point, but if I cannot easily convert to mining other altcoins at a profit, I will just transform this system into my new main PC and sell the extra GPUs.
Thanks in advance for your replies!
