Most 280x's are. I saw the reviews. If I were to buy a card I'd stick to the 7*** series cards. They overclock way better and will also benefit from Mantle.

If they are essentially the same card. Why do the 7970's overclock better? That doesn't make sense to me. They're either the same card or they're not. Is it caused by the memory being clocked higher? If so; then if you want a higher core clock, downclock the mem then overclock the core.... to get the same results? I don't see how a 7970 is going to do any better unless they made a change to their die making techniques which resulted in less OC ability. Anyone have any ideas?

Can we just take note that these brand new cards are running crappily optimized beta drivers... Most likely when the drivers have time to mature (and maybe some new BIOS updates from manufacturers:thumb: ) these cards will be running at their full potential. Currently a 280X will out perform (not marginally) a 7970ghz, WITH their crappy beta drivers and immature BIOS.

Don't think they will. Just like the other new AMD cards won't be able to beat their 7*** series cards when overclocked.

How well does the 7970ghz overclock? Seems like they arent much better than 280x tbh. Plus most 7970 have their voltage locked.

Its a rebranded 7970. Amd has been putting out these drivers for almost 2 years

Exactly, rebranded, not exactly the same GPU.
