Why are all the prices of 290/290x/280x etc so cheap now?

post #1 of 14
Thread Starter 
I was browsing through ebay and saw a bunch of good prices on 290 and 290x and was wondering is the mining craze in the US slowed down or folks just getting out of mining now? Discuss.

Difficulty in mining most Scrypt coins has elevated to the point that it is borderline unprofitable (factoring in electricity costs) to mine for them now.

Miners are exiting in droves and flooding eBay and second-hand markets with Tahiti and Hawaii GPUs.

The shock of supply exceeds demand, and thus now is the right time to buy a second-hand Radeon.

Buying a graphic card that has been run at 100% all the time seems like a very good idea.

7950s on Ebay are ending the bidding at $160-190. I want to grab another Rev 1 Windforce.

There is insufficient evidence to support the idea that running at full load 24/7 for months on end causes these cards to expire prematurely. You'll find quite a bit of anecdotal information of blown VRMs and the like but there is a bias towards defect/fault incidence when looking at it this way that is difficult to normalize (given the volume of these GPUs used for the purpose over the time period).

There are already a few articles alleging that the theory of mining cards being any less reliable than gaming cards is overstated at worst and unfounded at best.

But there's not much evidence to strictly say it doesn't, either. Just buy Asus, MSI, Gigabyte and/or ask for the original invoice and you'll be fine.

Agreed.

I sold the majority of my minning rigs (Total of 18 HD7950s) at the peak of the Litecoin craze in December and made a killing. That will be the only time you will be able to sell 8 month old tech at over 100% of what you paid for them lol. /bragging tongue.gif

But I kept 2 Windforce 7950s for my personal PC to "play games" on when I "had time". But all they did was mine away for another 5 months. I would say they are just as good as they were when I bought them even after 1 whole year of mining at 100% GPU utilization.
I had the fans on around 80% the whole time and a box fan pointed at the side of my PC. And thats the key here, you have to keep the cards cool. But isn't that with everything? car engines, other electronics, human beings....
Keep them cool and they will last.

I guess all I can say is that unless the prices are below 75% of what they are new, there would be absolutely no reason to pick one up.
High temps, excessive wear and unknown power amounts going through the cards are never good.
I can nor agree nor disagree.

I believe the 290 is trending at $330 or less, whereas it sells new for $430+ right now. The 290X is trending around $400 or less, whereas it sells new for about $570+. That's less than 75% or close enough...

At a sinister level, let's assume the cards have a dramatically reduced lifetime:

If they expire early enough in their meaningful depreciation cycle (let's say just before 3 years, when the card's probably worth <$150), you can send that sucker in and have a higher probability of receiving an aftermarket or newer-gen unit in RMA.
