I realise the buzz is all about this card but personally I'm interested to see how the performance holds up when they release the lower speced kepler cards.
Although its a bit wrong technically to compare scaling doing downwards, there was a tenancy for the cards to under perform expectations with Fermi.

if 256bit is ok for 5760x1080 I am sure 128bit will be fine for 1080p bus is over talked about and not that big of deal
 

Actually the stock cooler on the GTX 680 reference are really very well done this time around not that they were bad on the 580 but the 680 card runs cooler as is and has better cooling so the aftermarket is moot for me logic dictates it is a waste.
 

May i politely ask.Do you own one?
 



That's a bit blasé don't you think ?
How one card handles gaming with a 256 bit bus is not indicative of how another will get on with a smaller bus.
Then there is the small matter of the the games being played making a difference as well.

You really don't see a 128 bit bus being an issue to a card in the 6950/560 Ti segment ?

I think I owe russwood1488 a reply from the previous thread else the term 'islander' would be really harsh.
Sorry for the being late but I was busy reading reviews back then and only came upon your post when the thread was closed. 🙁
So as far as I remember you were talking about computation and gaming.Well,if that's the case,there's 2 ways to go.
1)OpenCL
2)DirectX11 Compute shading(Direct compute)
And out of all those games that gain from the compute performance of a card,relies heavily on the latter approach rather than OpenCL.Atleast I can't remember a title that used OpenCL.The GTX 680 may fail in OpenCL performance but strikes back big time on direct compute.
Here's what Anandtech observed :-

Finally, our last benchmark is once again looking at compute shader performance, this time through the Fluid simulation sample in the DirectX SDK.This program simulates the motion and interactions of a 16k particle fluid using a compute shader, with a choice of several different algorithms. In this case we’re using an (O)n^2 nearest neighbor method that is optimized by using shared memory to cache data.Redemption at last? In our final compute benchmark the GTX 680 finally shows that it can still succeed in some compute scenarios, taking a rather impressive lead over both the 7970 and the GTX 580. At this point it’s not particularly clear why the GTX 680 does so well here and only here, but the fact that this is a compute shader program as opposed to an OpenCL program may have something to do with it. NVIDIA needs solid compute shader performance for the games that use it; OpenCL performance however can take a backseat.

And for other audio/video transcoding performance,here also its got a nice improvement.As per Tom's :-
http://www.tomshardware.com/reviews/geforce-gtx-680-review-benchmark,3161-16.html
Therefore its fair enough to conclude its a wise step of ditching OpenCL to deliver the best gaming card as its still a long way ahead when OpenCL finally makes its way to gaming advancement but I do agree it has nice potential.
So Chill... if you hate tanning on the island shores,you know what? I hate it too. 😉
 

Do you really not see the logic GTX 680 does well @ 5760x1080p so GTX 680 will do just fine @ 1080P
 
So price to performance how does the 680 compare to:

The 7970?
GTX 580?
GTX590?
Radeon 6970?

I want to get this in SLI but I don't know if it's worth the money. It seems like for price it's on average with the 7970. For the price though and being a single GPU card I would think it would be faster than the 7970 just like the top of the line single GPU GTX 580 was a good bit faster then AMD's top of the line single GPU 6970. It seems like you have to spend 700 dollars on a dual GPU 690 to be much faster then the current AMD 7000 video cards.
 

Did you miss the part about the GTX 680 being significantly higher performing than the 7970 and significantly cheaper as well?
 


That just dosent even make sense in the context of my first comment.

Just to be crystal clear for you.
680 does well on its 256 bit bus with 2gb of Ram
I am concerned that the next card lower down the order may end up hobbled with a 128 bit bus.

I guess it wouldn't be to long, I just looked on Performance PC and and Frozen CPU and most of the companies have waterblocks out for the 7900 cards and it wasn't that long ago they were released.
