Agreed, you would think with the far better chip that Nvidia would simply design enough vrm (mosfets etc..) to tolerate huge overclocks. but they didn't. its like some other limiting factor came up.
I own Cayman and GF100, and GF110. like them all but Caymen can't keep up when GF110 has its power. Nvidia could have built a card for the ages, instead they built a big hog.
Unless I'm misunderstanding something, AMD is just asking Nvidia for official proof that the GTX 590 that they claimed to be the world's fastest card is indeed the world's fastest card.
It's not like AMD even went to any lengths to make it a marketing move, it was just some stupid blog post that is going to be missed by 99% of people who own computers.

Do people want to know an easy way to make the ATI 6990 much quieter?
1) Remove cooler shroud.
2) Take off heatsinks
3) Clean off the nasty crappy stock goo
4) Apply MX3 or similarly good thermal paste
5) Refit the heatsinks and cooler shroud
Say hello to up to -10 degrees and lower noise. Although you cant get around how bad the vertical blade fan design is, the thermal paste change should make a difference.
The fact of the matter is AMD should make sure its board partners use better thermal materials and fan designs. We should get your mentioned cooling improvements from the factory. As far as performance goes, the 590 and 6990 trade blows. I would say they're about equal as the typical mix of games out there favor either Nvidia or AMD chipset designs roughly equally. We have two great choices from Nvidia and AMD.

I blame expensive graphics nv ati cards.
This topic is a old trick, to let ppl know this cards are outiside and "" now we let ppl fight, whos and what and bla bla. And we colect our $$$ as much we can, to make another gpu ""
On both my Reference 5770s and MSI 560s, I got a drop of 6-10 degrees (8-10 degree drop at idle, around 5-6 at full load) by changing the paste to MX3. Yes, the MSI Twinfrozr which is already the best fansink design on the market IMO can be made even better with reapplying the thermal paste.
It isnt actually the thermal material thats to blame, because I'm very sure that my current MSIs already had MX3 on them because it was exactly the same color and consistency, but they use like 5x too much of it that it over insulates the GPU. Replace it with a smaller amount of MX3, and heat transfer improves a lot.
All of the AIB partners purely suck at applying thermal paste.
Also, I remember back with my 5770s that used a similar vapor chamber cooler that these new dual GPU cards do, the base was highly uneven and had lots of deep scratches on it. Reference coolers have always been nothing but pure crap to me, I only like to buy custom cooled ones now, and the MSI Cyclone + Twinfrozr coolers have made it to the top of my list for their unmatched quality.
Why? Its easier than changing the thermal paste on a CPU. I've changed the paste and coolers on my graphics cards more times than I have on the CPU, and nothing ever goes wrong. The MSI cards I currently have were the easiest, and they actually have the plastic tabs that go over the screwholes conveniently glued down around the screwholes.

Why the hell do noise and power consumption matter at this price point? For 99% of computers, yes, they do. Slower is much better, even if a lot slower, if it's quiet and sips power, no brainer. But when you hit the 700+ price point all that crap goes out the window.
If you can splurge over 400 on a GPU you can splurge the 60-120 is going to take to but a water cooling solution on the product anyways. These are 700 buck GPUs, you can afford it.

I believe most people buying the dual GPU card would buy TWO cards, if there was not an option to get about the same performance on single card.
For example if I bought TWO HD 6970 it would have cost me $740, the HD 6990 cost me $710. Anyway my setup is also more suitable for single Craphic Card.
The bottom line is if there was not market for such solution the cards would be never produced.

I agree. Tech Report pointed out that the 6990 had a higher TDP and at least the cards that he had were the exact opposite and by a decent margin.
i'm sorry, but i see "worlds fastest blablabla" on seemingly every press release in the tech community... this is really a non-issue.
to be fair neither amd nor nvidia have "the fastest grapics card" because both cards can beat the other in certian situations. this is all so silly...
Big B**ls of Fire!!! ehehehe
AMD did a great dual gpu solution ... no doubt
Nvidia did a so so solution that could be a monster ... but ended just " doing the job right "
Oh...your ass is grass and I've got the weed-whacker.
