well ,,, i dont like iwhat i saw. Only 17% better than HD7970 , and   everybody know the HD7970 can do a lot better than this.
Now the true question is:
 Who is better at max OC?
 I want to know if GTX6860 can better in OC.

 I hope you are not talking about me. Becouse i dont have Nvidia. i jst want a fair comparation. I think nvidia make a Auto-overclock , unfair.
Streange thing too ,is the idle clock at 702Mhz , and the normal operation a 1000mhz and than 1058mhz at full load.This looks like a cheat system .I think the original specs of gtx680 was more slower than hd7970 ,but if this auto-OC ,and unknowed OC performance ,its hard to say what is better.
 i think the gtx680 dont have more than 30% in OC ,and the AMD can do a lot more than 30% in OC. this means the both GPUs have the same performance, but Nvidia only to say they have the best card ,put more agressive clock in default on to say they have the best gpu on the market .As 70% of user dont make OC ,this means they will prefer to buy a fast GPU in deafult and not a slower GPU  in deafult clock ,but this same GPU can make a OC  with 70% . 
I prefer to buy a GPU with a OC from Gigabyte or sapphire ,and dont make any OC on my gpu .

You are a idiot , you dont know anything about strategy, you think the Nvidia is the best becouse they puted a high deault clock.
 Dont forget,  even AMD and Nvidia ,leave more room to let the companys like gigabyte or sapphire ,putting their deaulft clock.
 Its prtty nomal to see a HD7970 with more than 1Ghz, but this is part of the strategy .AMD show a reference with 925Mhz ,and and for example, Sapphire make  the same GPU with a beter cooler and with 1050Mhz of default clock.
 This is for sell more. You are right to think Even amd and Nvidia put the  deaful clock as stable as posible. But they think about the companys too.
  I am not sure if the Nvidia can do 40% more in OC, and this is m point.
 GTX680 is  in AVG 18% more fast than AMD, but everybody know the HD7970 can do a lot more with OC,
 Now try to understand , if the HD7970 can do 40% or 50% more in OC ,this means the deafult clock are too lower than is possible. There are a lot peaple worryed about to make a OC ,especialy when you know some GPUs dont have a huge OC.
 I will give to you my GPU as example.
 I have HD6870 from Sapphire, 875Mhz with 1250Mhz of memory.
 I already tested my best OC is 890Mhz on core and 1255Mhz of memory.
I cant use anu software mod for voltage.
 This means my card is not so save for OC and the Sapphire locked the OC.
 But as i said there are  others companys that allow the OC ,but in mosted of cases we cant to get 50% in OC.
 But lets say, the deafult of my GPU were 600Mhz and not 875Mhz, Normaly everybody will get a lot worried about to get 1Ghz in OC.And this OC its a HUGE OC.
  I will not buy a GPU to make OC, but its a lot more confortable to know your GPU can do 50% more OC .
 So if you need more 20% ,its Ok,becouse you are a lot far away from the limit.
 But  now talking about the GTX680.
 I think GTX680 is fast as HD7970 , but as everybody didnt know about the specs ,now everybody thinks the Nvidia “NEVER” changed the deafult clocks.
 Now we know the GTX680 can run at 1Ghz, and with this clock ,can win the battle.
 But  my logic its pretty simple, if the GTX680 cant to do 40% or 50% like the HD7970 does,this means the GTX680 is fast like HD7970 ,but nvidia choose to put a high deafult clock.
 You are saying i hate Nvidia, this is not the true, becouse i want to have the 3d vision and i want a fast GPU to run my games with performance and Quality, what AMD dont have a Quality in 3D glasses.
 But you are acting like a fanatic football fan. and i am acting like analyst person.
 the HD7970 is pretty save at 1Ghz too ,but part of the stratagy of the GPU is, to make it with Lower temps, lower comsumption ,lower noise. And with 1Ghz this means ,is needed a little more  cooler and the GPU will use more energy.
 Todays GPUs problem are the comsumption ,that is why AMD puted at 925Mhz, and to give more room to the companys.
The true is, if the GTX680 cant to  offer the same OC than HD7970 does,  you jus need to make the math and to understand the GTX680 was clocked a little higher to beat HD7970 in deafult clock ,but at maximum ,  both does the same performance.
 So you are acting like a Fanboy not me. i am just saying all this things ,becouse if i were Nvidia i used this stratagy.
70% of the peaple dont like to make OC , and this 70% trust 97% in the deafult clock, so for these players its pretty important to have a fast deafult GPU than a  slower GPU in the deafult Clock ,but with a HUGE OC, becouse  we lose the warranty.
I am prety sure the GTX680 is more fast than HD7970 ,but only becouse the GTX680 have the deafult more high, and if both gpus at max OC ,both have the same performance.
But to prove i am right or wrong, we must to know if the gtx680 can make the same OC than HD7970 , if the GTX680 does 10% less in OC, this means the deafult clock was upped to 10% high.
 You can like of some company ,but you need to learn more about strategy.
 i prefer to but a GPU with high deafult clock with only 5% in OC, (this means the GPU was tested enough and can run at the limit all the time)
Than to buy a GPU with low deafult clock ,but with a 70% in OC.
 This is my point. Noone say the HD7970 with 1400Mhz is better than GTX680 ,becouse the deafult clock is what better, got my point?
 Lets say the HD7970 can beat the gtx680 in performance  in OC ,but the GTX680 will be the winner becouse is the deafult clock what metters for 90% of users.
 So if the AMD puted the HD7970 at 1,2Ghz as deafult clock ,but only with 8% in OC , probably the  GTX680 coulnd´t not beat the HD7970.
I think now you can understand my point of view.

Sorry for my english , i tryed to use the google ,but sometimes the translations from google dont make any sense. English to my language /from my language to english.

I AM 100% agreeing with you… the 7970 wins this round for sure…

Your viewpoint was way over done… AMD should have stock clocked the 7970 at least to 1000core.  Exactly why nvidia is putting there price lower then the 7970.  If AMD was to lower their price, 7970 is a much better option…
