I gave up on getting a full on mining rig. It's pretty much not worth it with the markup on pretty much all GPUs, adds like $1200-2000 more, which means another month of uncertainty. I'm just gonna use an old i5 4590 PC and my two 1080 Ti's. This lowers my cost to only $2300 and I'll be happy to break even and then just use them on my main PC with SLI.

Side note, the MSI Twin Frozr 6 and Gigabyte Aorus are so quiet even in open air. I'm actually quite surprised and you could probably sleep next to it. My Gigabyte 980 Ti with the older cooler is so much louder.

EDIT: Crap, I'm running ~700W on a 750W PSU. Going to need to up my PSU. Probably 850-1000W preferably gold+. Any good PSU deals going on?

Wow, PSU got the same mining treatment. everything 1000W+ is pretty much sold out. Only a trickle of 850W but it's gonna be running tight and I can't overclock.

I've preferred to not to run video cards at their power limits, the extra performance often not worth the extra power consumption needed or the hassle in sourcing more powerful PSUs. Which coin are you currently mining?

I have a spare computer, I want to give this a go.

I currently have an i7 3770k with an Intel DZ77k-GA motherboard and 16 gigs RAM

I can plug in 3 Video card into that motherboard. Which card should I get and what should I do to get started.

It currently has a 750 Watt power supply. I also have a 1000 watt power supply if that’s require.

I don’t have a wallet or know anything about mining. How do I maximize the profit.

Don't pay too much for video cards.
The video cards for me alone, will be $8K.

I limit my GPU to about 70% power. It stays 10 degrees cooler, and does not struggle anymore. It still mines (roughly) the same amount. Every card is different, you can find the sweet spot on yours.

Same with my CPU. I reduce power. It makes a huge difference. It is the difference of my room being a sauna, and being comfortable.

I don’t mind paying for video cards if it yields a decent return over a year. I’m only looking at 3 cards just to test the waters.

If you can find some, 1080ti are generating USD $250/month as of today.

How much Memory should the card have? I’m not a gamer, I have no idea at what I’m buying.

3 cards generating $250 per month, I can break even (cost of cards) in a year.

Any particular brand I should shoot for?

To make it simple for you, depending on your budget, buy either 1070, 1070ti or 1080ti. You can buy diffrent ones if you dont find in stock, it rly does t matter. They all have pretty similar ROI, cheaper one have a bit better ROI but 1080ti will gives you more money in the long run

Long run?

How long are we talking about, if we take the volatility out of the equation.

The 6 GPU rig that I'm building only requires a min 4GB DDR4 ram and an Intel G3900 or better.
Basically, the GPUs are running and nothing else is going on.

1080ti will recoup more money in the used market, if you need to sell them.

3 1080ti will give you the same monthly profit for around the same price but it'll be way easier to buy/resell and you can buy them from reputable buyers and not worry about failing hardware with little support/warranty. Disclaimer i dont know much about the process of buying the S9 and the warranty/support but i feel 1080ti are a much safer investment for almost the same return
My 1080 TI can hash 8 to 10 USD per day so I guess your estimate is pretty close. The issue is getting a 1080 TI at a decent price.

Just currently on nicehash until I read up on the different pools. Is 700W load fine with a 750W PSU? Maybe I can get a 850W PSU if that lessens the load a bit.

$200 average markup is what I paid.
