If the following seems preposterous that's because my understanding of these things is limited, hence the question.
I recently invested in an XFX R9 280x to replace my ageing 6970. When it arrived and I installed it (properly I might add, by uninstalling drivers then running a driver sweeping program before reinstalling the new card) I had on-screen flickering, vertical wobble up and down like an old tv and cross screen tearing. I tried a driver wipe, again and when the problem remained I sent the card back.
My wholesaler benched the card and deemed it faulty sent me a brand new card in a box. I installed the new card and it, to my shock, did exactly the same thing only worse. I sent the 2nd card back and the wholesaler again bench checked it and discovered that it too was broken. This time I took store credit instead of a replacement card and now I don't know what to do.
I don't much believe in coincidences. The odds of getting two shagged cards straight out of the box must be astronomical so I'm skittish about getting another 280x from the wholesaler. If something goes wrong with it we're at a point where they're going to think I'm wrecking them somehow and I'll lose my money.
Can anyone tell me if there's a chance there's something the matter with my rig that might be stuffing up these cards or am I just the unluckiest person in the world to get two broken cards in a row?
Two things to consider: I don't overclock and have not stressed either new card unduly. I just plugged them in and they were shot from the get-go. Both times I've put my 6970 back in and it's run perfectly.
Really keen to hear what people think.
