Refurbished card are all card returned no matter the reason. Refurbished products are generally bench tested and certified by the authorized service centers of the company and then re-packaged, labeled as a Refurbished Product. Most mechanical fixes are by trained technicians who work for the original company that distributed the product. These cards should work without problem.
I will try with two cards first and will see what's the ROI would be, maybe if i'm satisfied I'll continue expanding 
what series will you buy? just share what I experienced with R9 290x and R9 390, I have one 290x and 390 I bought in 2017. 290x still mine in Ethash until now but 390[1] only lasted 4 months after buying and damaged.
1. R9 390 has freeze problem when claymore runs and hash rate decrease also system restart itself every 5 minutes after mining. I tried fixing this card (390) like changing the processor paste, heating the processor with a heat gun and it could not be fixed.
Not exactly GPUs but i bought a refurbished LCD monitor 2 years ago. It was a huge sale on NewEgg and they were supposedly offering 50% off. I still use the same monitor today and am happy with it. Just imagine how much better buying refurbished items is compared to buying second hand from people whom you don't know what they did to the item. At least you can rest assured that you are buying from companies want to have a good reputation and not some random person who could have rubbed that all over his as$.
I think you can use refurbished card. As long as that's in good condition and still have good looking. I was use that too in my rig, and have been 2 years from buy it. Sorry my bad english 
I think that you should try to expand your rigs in any case, as the prices for the repaired cards are really low. The risk is small, and if everything is in order, you will get a good profit.
This is exactly what I am thinking of doing, and I simply do not really care if they are refurbished, second hand or new ones, as long as I get them on a deal
I am not affected by the current manipulated market, because if everything goes according to predictions and plans I would be making a passive KILLING I prefer to invest in something like cryptocurrencies, rather than give my money to a bank with 0.8% interest rate(for the lulz).I will try with two cards first and will see what's the ROI would be, maybe if i'm satisfied I'll continue expanding

agree with @MinedTangerine
yeah, for now, those price isn't worth if see from mining situations too risky because we don't know how long again these cards can survive (durability) at mining rig but if hash rate, of course is no doubt.

Those cards are built like tanks. I've purchased many 280X's second hand and then resold them at, near, or above what I paid for them depending on the market fluctuations. I disagree with what some other people said about .10 cent electricity. Just plug in your wattage/hash power figures to various calculators to figure out what is profitable.
I have R9 290X. the card is great but its a power hog. And newer miners are droping support for them. So its questionable if its worth it. At 250 EUR its definitelly not. I can get RX 580 cards for that price (second hand)
for AMD especially R9 Series indeed has a problem with Power consumption and secondhand when compared with RX series but R9 series has hashrate could compete with another card in Ethash algo also has a cheaper price.

You have only named old cards. If you have cheap electricity the only cards I would get are the power hungry R9 beasts. If not I would look more into the Nvidia 10 series, like the 1050 ti and 1060 being the sweet spot by not using 100% of their power in MSI.
A mining computer with 8 x 1050 ti can give you about 1300 sol/s with undervolting of the power at just 71-78% in MSI afterburner and the consumption of only 500 watt together with the motherboard. If you can find those cheap, which actually you can now I think it is a good deal.

For the most part, it would appear not. However, if a real and decent warranty is offered, it could potentially be worthwhile from a price and risk point.
I have 2 270x which i bought in december under 60eu, i roied them in about to weeks back then. They are bit power hungry but as long as u have cheap electricity ( i have a flat fare) they will be making a profit, not much these days though. They dont have many good algos but here is my combined hashrates with what i mine, mind no bios mod.
criptonight v7 : 930h
equihash: 395h
neoscrypt: 1150h
ethereum: 21mh
i run them at 80% so the power draw is around 300w forr both.

When are nVidia and Amd gonna announce their new products and will be available to the public? maybe then the prices of the gpus will dip a bit further, hopefully
for AMD card no one knows and yet no news but for NVIDIA will release 11 series in July it's still rumors. I think RX480/580 and 1070ti/1080ti are still relevant maybe then the prices of the gpus will dip a bit further, hopefully
Hello guys!
I found a distributor, who sells refurbished cards - mainly AMD Sapphire:
R9 270X 2G DDR5 - 75 euros
R9 285 2G GDDR5 - 110 euros
Sapphire NITRO R9 380 2GB GDDR5 - 125 euros
NITRO R9 380 4G GDDR5 - 140 euros
NITRO R9 380X 4GB GDDR5 - 150 euros
NITRO R9 390 8GB GDDR5- 220 euros
TRI-X R9 290X 8GB GDDR5 - 250euros
R9 390X 8GB GDDR5 - 270euros
I am thinking of expanding my rigs, simply because these cards, at least in my opinion are kinda cheap. For the past couple of months I have been mining mainly the cryptonight algos, mainly heavy. I am currently with RX580s and they perform just great. As far as I know, AMD cards are great for this algorithm, but I was not able to find any information regarding the hashrate of the above mentioned cards.
I would be really grateful, if you guys are currently mining with these cards and share your thoughts.
I am making my own researches, ofc, won't rely solely on your opinion, but I just want to know how these cards perform under cryptonight-heavy simply because I cannot find any information...
Your replies would be greatly appreciated!
As always, thanks for taking the time to read my thread and I wish you profitable mining!
If you buy new GPU cards it will run long life but refurbished cards are not supporting to you because day by day updated in hash rate it is increasing the efficiency of GPU so better you should buy new products you have some idea about the new arrivals. If you feel it is more convenient to new GPU you can choose this cards. I found a distributor, who sells refurbished cards - mainly AMD Sapphire:

From what I have seen recently, the nVidia 1180 card at the least is set to be released sometime in Q3 of this year, and I’m not sure about what the situation is with AMD right now- it depends how well the new generation of cards mine that will determine where GPU prices move from here. If the new cards aren’t good at mining compared to this generation, then prices for the 1000 series cards might just stay where they are now or go up.
Hmm I found some stats regarding the speed on the more expensive ones and tbh, as I did some simple calculations, it seems it may not be worth it that much in the end...

You don't know how long these refurbished cards have been used by people. Maybe they are almost dead. They just look new and you have no protection for them. It's like a gamble.
Of course, if they can live in your hands for 6 months, you should be earning.

R9 series has hungry power consumption and fast temperature rise so you should give an additional fan but R9 series excellent in Ethash algo also R9 series has 512 bit so if Dag file/size up to 4gb then R9 4gb will have no effect and still can to mine (ethash algo)
