I wouldn't think so. If it hasn't died yet, I doubt it will. Usually, if a cards gonna go it will be already dead. Just so ya know the only time it's been OC'ed is for the review and when I tested for fun. Has run at it's stock clock 24/7. But she will scream if you slap her.
Edit: Just looked it up. Bought it around the fifth of January. So, just over six months of use. Nary a niggle with it. Save for some bad drivers. I'm using 13.4's right now just finished Bioshock Infinite and Tomb Raider with it. Flawless.
I do find graphics corruption with it on some drivers, but changing drivers fixed it.
Edit: My CPU is a little on the weak side. But here is a
Valley bench I did in February.
