I'm about to get a R9 280X graphic card that was used for mining in that coin stuff (don't really know about it )
I'm getting 2.5 years warranty with him and he will cost me $254
So my question is if it is worth getting a mining card that has 2.5 year warranty?
I mean what could happen I have 2.5 year warranty.

I am not talking about the solder joint, I am talking about the stress on the semiconductors. They solder joints are the least of the problems, these can be toasted back in working conditions in an oven, but the semiconductors can't be just cooked into working order!
the same semiconductors that need temps of over 800c to diffuse in the first place?

So the card has run 24/7 for 6 months at steady temp, no cycling what so ever... Almost as good as new.It is the temp cycling that cracks the solder joints, steady temp doesn't do a thing (the IMC layers grow a bit, but not much in 6 months anyways)
And if the miner knew what he was doing the card hasn't been overclocked or overvolted, heck if he fine tuned it he would have undervolted it to increase the hash/Whr ratio...

If the card was used for mining then it basically means that it has been running at 100% constantly since it was bought. This is something that cards inherently aren't designed to do. They are designed to give a gamer that oomph whenever he needs it and then calm down and run cool and slow. This card however has been running the whole time under boost clock at temperatures over 60°C
It is possible that this card is or will soon start to suffer from graphics fatigue, this means that even at far above playable farmerates the whole gaming quality is going to feel very sluggish... almost like the whole system is tired.
People are now selling off their high end radeons like hot cakes because bitcoin mining is no longer viable.
So... uh.. no. Not for anything over 200 bucks, even that is pushing it.

i personally wouldn't get a mined R9 280x. Its lifespan is already largely reduced. The warranty only applies if the warranty sticker has not been removed. Check if it is still there. Even if you have warranty, if the used card fails, you have to pay shipping for a replacement which will cost more than getting a new R9 280X anyway.

it’s like playing the lottery, you never know what you are going to get, how long it was used and what kind of condition the card is going to be in. Personally I would spend an extra $60 and get a brand new 280X. I hope this helps.
