Tread lightly with higher OCs.

If they made 8GB versions of this card, I'd be really impressed.

I'm ready with the credit card if it's released tomorrow.

Most of the cards that died in the thread were closer to 900Mhz than to 1Ghz, and most were using 1.05-1.1v

XS too

I'm not sure where you are getting your "safe" figures from.

It looked more like 1.2V + power limit disabled + Furmark burn in was causing it from what I've read. There's always a small failure rate for every card though even at normal voltages and I think some of those are being thrown in there. Even if they weren't running Furmark at the moment it died, prior runs of it at high voltages could of already damaged it in the past. I agree that it's not as safe as a 580 is to over-volt but don't put unnatural stress(Furmark/OCCT) on the VRMS if you want to overclock.

Anybody else not see the point in the 6970 vs 570 OC capability argument. There is marginal relevance at best to the 6990 and its yet to be released competitor, the 590. Furthermore, maybe at eyefinity type resolutions you need 3 or 4Gbs to remove any possibility of a bottleneck, but 2gbs WILL afford you more options for AA and the like even at 1200p/1600p.

On topic, did AMD confirm the 8th or is the release date still just a rumor? Though... I may wait for the 590 before deciding on either card.

If you look above, you'll see that 2GB of memory didn't help at all and actually did worse at 2560x1600. If you're going triple 1080p or above, even 2GB isn't enough, you need 3GB. You'll also need 3-4 way in which case Xfire will be frame data bottlenecked since you can only use one bridge across any two cards at that point.

The 6990 is pointless since it performs worse than dual 6950s most of the time and 570s beat it in Battleforge, HAWX, CIV5, Dirt2(even the 560s), Mass Effect 2, Wolfenstein, Alien Vs Pred, Metro 2033, CoD6, Just Cause 2, Batman, BC2, 3DMark Vantage/11 and Unigine Heaven. Physics, Tessellation, OpenCL, CUDAvsStream and 3D all perform better on them as well.

Not to mention how poor all of ATI's cards are in compute performance(OpenCL) by losing to a single 560...
