Is the 680 a flagship GPU and can an overclocked 7970 meet or beat it

there's a lot of people claiming 2 things:the 680 isn't a flagship GPU do you think there will be a 685, and can an OC'd 7970 can meet or beat a stock 680
opinions????

There is some speculation that when Nvidia saw what the HD 7970 could do they changed up the release schedule and released what would have been the GTX 670 as the GTX 680 and they could still charge $500 for it. When they first released the 680 I believed it was the model that would have been the 670 but now I'm not so sure since they can't even get decent enough yields from TSMC to supply demand. The real 680 would have had even less yields because the transistor count would have been much larger (all based on rumors). Now it looks like there will be a GTX 780 released some time next year and that will be the true Kepler flagship but for now the 680 is the fastest Nvidia single GPU.

Why do you want a comparison with an overclocked HD 7970 and a non-oveclocked DTX 680?

From what I read on other forums and their testing, clocked the same speed or more the 7970 is on par/ trades blows with the 680. This is attributable to the 7970's good overhead in clocking.

look at this review on the lightning 7970. It has almost 1100 stock speed.

The better comparison is not an OCed 7970 to a non-OCed 680, but a "max OC" of each. The 680 has built-in OCing, just like Intel's turbo boost, so it has less pure overclock headroom than the 7970. But the 7970 runs quite cool at its stock speeds, and (like all of the HD 7000 series) has a lot of OC headroom. Once you overclock both cards to their maximum speeds, they are very competitive:

edit: note also that the link above is using just Catalyst to OC the AMD card, rather than tweak utilities like Trixx or Afterburner, which allow clock speeds of 1250 MHz+.

To answer your questions the 7970 in the scenario you put is plenty capable of beating a 680, this is game and resolution dependant though and which card wins chops and changes quite a lot. Either card would be a good choice.

The 680 is 100% not a flagship chip. It is designated as GK104. The chip that people are referring to when they say there is a better chip is the GK110.
For the time being Nvidia are choosing to keep these chips out of the general consumer market place because basically they don't need to use them in the consumer market as the GK104 is powerful enough to compete against the 7970.
The GK110 can command a much higher price when configured and sold as a professional computing card.

I've heard that the 680 was leaps and bounds better than the 7970 so it would make sense to not OC them both because the 680 would win (if user reviews are true) if that makes any sense....
