What do you mean by the market is uncertain? The job market, or the way prices are going through the roof? Either way, it doesn't matter how hard you run the card, if the best one out of four lasts only two weeks, it's junk. You can't break even due to having to pay shipping multiple times on a card that won't work. Basically I'm thinking of buying a similar card latter (my poor, poor, bank account). but by a different manufacturer...Sapphire, or maybe MSI. The only problem? When I was comparing cards, I noticed that all of the HD 7970 cards were highlighted in red. I can't find a key for it, so I don't know if that means the cards are unsuitable for mining or what. Some information on it would be nice.

Don't those XFX cards have lifetime warranties for the original buyer?  I'd say run it hard.  Although I'm not so sure putting money into hardware is the best idea if you are on limited income.  The market is so uncertain...

I got a few 7950 recently and they were a lot trickier to setup then my 5870's. All kinds of driver issues and what not. But i got them to work in the end.

Can you post what you did to get them to work?

Because my current card was needing to be replaced, and because I wanted to get into bit mining, I decided on purchasing a HD 7970. This is a bit better than buying a HD 5970 because people are charging $400 for a used card...that would have only cost $200 brand new. Ahh...no. The fact it's used means if it messes up I'm out $400 bucks, and since that measly amount is enough to set me back for a couple of months, I, literally, can't afford that to happen (being on social security sucks...the job market is helping things either Sad ). Also, please whatever you do, please do not get me started about the people who can afford to throw around $30,000, because that will start an argument that no one wants to hear.

Anyway, poverty woes aside, Murphey's Law also seems to have gone into full force here the last four months, because who here doesn't like to have things blowing up in their face all the time? The card I purchased on December 24 (Merry Christmas everyone) has been replaced twice already, and now for a third time. The worse part? This is the best one of the lot...it took an entire two weeks to quit working (not showing up in Device Manager), plus it had a damaged tab where the top screw went in. As for the others...well the record is less than a minute for the last card (power fault...the computer wouldn't even start with the card installed), and as for the other it only took around five hours for it to give up working.

Noticing a pattern here? I have been told that there has been a bad batch of cards, and they just realized it in March (funny...I realized something was wrong back in January shortly after getting the computer built, and installed). As a result I have to ask this question: am I just ridiculously unlucky, or is the manufacture the worst company in the world when it comes to manufacturing cards. The fact their headquarters is based in Hong Kong somehow seems to answer that for me. Still, I need a second opinion, which is why I am asking if the card can be used for mining, and if not, would it at least serve as an okay gaming card without giving up on me?

Also, minor detail, I do have a single GTX 470 installed for gaming so that I don't have to take the Radeon card off from data mining. It is possible that the driver conflict which regulates voltages, etc. might be the reason I've had so many problems. Even so how can an Nvidia driver interfere with a Radeon card when, you know, the driver technically shouldn't even recognize the card since it was made by a different manufacturer? Also, kudos if you read all this, and more so if you respond with something useful. Right now I'd appreciate just about any guiding light at the moment.
