Purchasing GPUs for Crypto Mining

Welcome back to the Hobbyist Miner Channel where we discuss all things related to cryptocurrency mining. Months ago, I shared in a video that I decided to stop buying GPUs because my main goal was to finish building my shed. Now that the shed is done and packed full, I’m excited to say that we’re back on our path to buying GPUs.

The Search for the Perfect GPU

When it comes to hunting for graphics cards, it’s a gamble on platforms like eBay, OfferUp, or even Facebook Marketplace. These platforms can be addictive and risky with people posting deals that can be too good to pass up. However, I’ve made efforts to stay off these platforms to avoid trouble.

Today, I am on my way to pick up three new graphics cards – two 30 70s and a 30 60 TI. The seller is a previous miner who I found on Facebook Marketplace. Their profile showed different GPUs, motherboards, power supplies for sale, so I thought to myself ‘why not give it a shot?’

Strategically Negotiating GPU Prices

I made offers, a hundred dollars less on every single GPU. Each of them were already discounted, so I offered $325 for the 30 70s and $300 for the 30 60 TI. The seller agreed to each of my offers, giving me a total spending of $950 for 2 units of the 30 70s and a 30 60 TI. Considering prices from months back, I feel like I got a pretty good deal.

Bringing My New GPUs Home

After making my purchase, I then brought the GPUs home to test them on my bench, ensuring their performance is up to par. Initially, I plan on mining Ethereum, but in the near future, I foresee them working on platforms like Flux and Ergo.

Unboxing My GPUs

I purchased several different types of graphics cards, including the EVGA for The Win 3 36 DTI, the PNY GeForce RTX 3070, and the Asus GeForce RTX 3060 TI, among others. Depending on the model, some required two eight-pin power connectors, whereas others required a single twelve-pin power connector.

Making the Decision to Buy More GPUs

You may be asking why I suddenly decided to purchase more GPUs. The answer is simple. First, my shed is complete. Second, GPU prices in the used market have recently come down significantly. Third, I had the cash available to make the purchase.

I decided to go with current generation GPUs, the 3000 series, as they are much more efficient and powerful compared to the older 10 or 20 series. I specifically searched for 30 60 TI’s and 30 70s due to their performance across different algorithms.

Setting Up the Mining Rig

I allocated the newly bought 3000 series GPUs to a particular server case, the Minor Dude Extreme, which can house up to eight GPUs. With some swapping and adjusting, I was able to fit all the new GPUs into the case.

GPU Overclocking on Hive OS

Before we end this video, let’s discuss the overclocking settings in Hive OS. It took me a while to find the ‘sweet spot’ for each of my GPUs. Every card was treated independently, and even with the same memory, the overclock settings varied.


So there we have it, four new GPUs added to the rig and ready to start mining. And with the Ethereum merge just around the corner, it seems my decision to buy a new batch of GPUs couldn’t have come at a better time.

As always, thanks for joining me today. If you enjoyed today’s video, please remember to give it a thumbs up, and if you haven’t already, don’t forget to subscribe.

  1. @hobbyistminer was the contest completed accurately?
    I noticed that comments didn't appear if you typed hashtag flux. I'm avoiding the actual symbol and flux otherwise this comment will not be visible.
    Also, I noticed the winners only had the word "flux" in their comments or hashtag then a space then flux and not following your directions of hashtag flux in the video.
    Just very odd…..

  2. I bought some 5700XT's recently, right before everything crashed even further :')
    oh well, long story short, got new cards, woo! now if only my rig would work, it keeps showing "Dead gpu" in team red miner, im suspecting its the motherboard…

  3. Hy there,

    one quick question, what about the A2000 graphics cards ? They are also about 400-500$ and are more efficient ?

    If i am not paying attention reselling the cards, would you also recommend 3060 ti and 3070s ?

    thx in advance.

    Greetings from europe

  4. I purchased a few cards about 2 months ago but holding off any more until the prices come down. I purchased new 1660 Supers for $189 direct from EVGA and a Used (new in-box) EVGA 3070 for $400 and a 3060 for $280 locally from FB marketplace. But now that the prices are coming down I would not pay this much for these same cards today.

    What is interesting is a lot of people I talk to on FB Market place do not know about the merge. They are listing cards for more than I can buy them new. Its kind of fun to gently and respectfully message them and let them know what is going on. All of them have been appreciative of the info and many have changed their listing after I let them know. This is not a bargaining tactic just letting them know why their cards might be selling.

  5. I've managed to get my 6700xts overclocked to 46.2mh @71w in hiveos on etc at the moment so I'm going to point that one to neoxa and my 1660 supers are going to flux as I can get them around 78w @ 24.7sols which is on par to my 2060 that does 122w at 37.8sols. 0.30 Sol's/w isn't too bad. But I'm looking for some 30 series soon they are still expensive here.
