Are ex-mining cards worth getting?

I'm seeing a lot of ~$100 RX470/480/570/580 ect flooding ebay. Obviously most of these are old miner cards. I've been due to upgrade my HD 7850s forever, which I bought the first one for $140 new and the second for like $80 used. I usually get the new mid-range cards in the $150 range, but that hasn't been possible with the state of inflated prices over the past few years. Now finally seems like a great time to shop mid-range cards. With new ones already sub-$150, would it worth taking a chance on a used one? Obviously I'm worried about worn out capacitors and fans (the two likely components that wear out).

I'd like to hear some feedback from both penny pinching gamers and miners alike.

I's also likely that I'll be doing a whole platform upgrade on my main rig in a few months...probably to AM4. I don't play the very newest games. Mostly good ones from the bargain bin 1-2+ years old.

Hi,
Paypal and ebay have pretty good protections so you can always send it back if you have issues with it

Most problems with mining cards are obvious
One never knows the farms cooling and one knows they were pushed 24/7...
Get lots of images of it before.

I am fine with mining cards. But I would prefer to get one from a site like this then eBay.

The main thing is just get one with warranty. I got one off CL recently. Had two years warranty with EVGA so I know if there are any issues I'm good.

Pick a brand that has a good reputation for their RMA service. That's my top priority for buying used.

Which means as much as I love Asus products I'm scared of them the way they often handle rmas.

As an ex-miner and current gamer, this is good advice.

Asus makes high quality GPU's with some of the best quality cooling solutions of any video card I came across. But if their warranty is lacking it's not worth buying.

I had ~35k worth of video cards during my heyday mining, and in my experience Gigabyte and Asus cards have proven themselves to be the most hardy and resilient overall. Though do keep in mind that any product will fail if not maintained by the operator, doubly so when under high stress.

That's a lot of gpus. Interesting to hear your results with those brands. I have had good success with gigabyte cards and they usually have great coolers. This makes me more confident to buy them.

I wouldn't buy a card from a random unless they provided proof that the GPUs were mined on properly. A mining card doesn't have that hard of a life assuming they optimized the power/clockspeed ratio. If a miner is paying for power and GPU's they need the GPUs to crunch as much data as possible without drawing too much power and without any down time. In the long run a lower core clock, voltage and TDP are critical for making money, especially as ETH got harder to mine. Plus ETH wasn't super core intensive, it's actually hardest on the ram and the ram is likely to be the hardest component to break. Sure the fans are probably worn out but the same place makes all GPU fans so they should be easy to replace if you know the S/N (on the back of the fan).


I'd buy any working GPU if the price is right but for mining cards as long as they weren't abused I don't see an issue with paying normal used prices.

Does that apply to both Nvidia and AMD cards?

Again: Applicable to both Nvidia and AMD? I was under the impression that EVGA is the 'go-to' card for Nvidia and Sapphire is the 'equivalent' 'go-to' for AMD/Radeon cards. This is the first time I've read Asus and Gigabyte recommended - and does it matter what model or is certain ones?

I'm looking for a used card and wonder what to look for (I posted a separate thread on this). Also, how does one know if someone was properly mining their card.

I was wondering if someone has in their description 'modded bios to boost clock' whether that is normal or because the card was mined previously? Is it something to worry about? I read that mining cards aren't necessarily bad because often they undervolt the cards but there seems to be a difference of opinion - seems like 50% say 'don't worry' whereas the other half of people say to avoid mining cards.

What's a scenario or example of a mining card being abused? What are signs to look for?

Thanks.

It totaly depends that how the miner used the card, you can only judge the card after physically checking the performance. You can give a try to those card as ebay gives full refund if the products not working properly

Relying on eBay's refund policy is not a foolproof way of doing things. It may be better than buying on Craigslist but there are as many horror stories with eBay refunds as there are happily refunded customers. As a customer buying on eBay I was personally ripped off by a seller who posted a convincing argument during the dispute resolution process.

Just urging caution is all. If the deal looks to good to be true it's best to pass on it.
