Are there any reviews of Skyrim with heavy graphical mods @ 2560x1600?
I just don't think 2Gb of VRAM is enough but there's no evidence.

Makes much more sense. The reason these cards were never going to be modded BIOS versions of original 7970s is the TDP, as someone mentioned earlier. It needs to be a higher quality version of the chip to be able to produce the higher speeds without ruining the TDP.
Looking forward to seeing how high these will clock, especially if it's the same percentage as current 7970s. If it is then we can expect 1350-1400Mhz.

I think the sensible thing to do is wait for the release of actual card and the reviews for them from well-known reviewers. As setting expectation too high base on rumours alone could lead to disappointment, just like the 6950 and 6970 back then.
Also, there's no guarantee that AMD wouldn't charge 7970's launch price for these GHz edition card...afterall, they did stack their pricing on top of last gen's card, and sell the slower than 6850 7770 for £130.

I was referring to the overhyped pre-release rumour of 6970 being faster and great deal cheaper than GTX580^
The 6950 certainly wasn't a disappointment when it got released though!
A £200 card that thought it was a £300 one.
But to be fair the ability to unlock of the 6950 won people that were disappointed back, and nobody was really bothered with paying the extra for the 6970 except until later when 6950 beginning to unable to unlock

You mean the one where someone faked a bunch of benchmarks for them and got banned because of it?

There was also Raven who had a supposed source that said the 6970 was gonna be the faster card.

Think it originated from one topic, and then it spread across the forums. Before this go off-topic, the point I was making is wait for actual reviews when the cards are available to see the performance, overclock capability, and most importantly...the UK price. It is simply that.

We are waiting for official reviews, but someone saying "If blah-blah-blah, Then blah-blah-blah" they are just expressing a logical thought process and not starting a rumour.
No one has promised better binning, just discussed the possibility and what it could mean to end users.

***UPDATE***
AMD Radeon HD 7970 GHz Edition "Tahiti XT2" Detailed
'We've known since May, the existence of a new high-end single-GPU graphics card SKU in the works, at AMD. Called the Radeon HD 7970 GHz Edition, the SKU is being designed to regain AMD's competitiveness against NVIDIA's GeForce GTX 680. We're hearing a few additional details about the SKU. To begin with, AMD has worked with TSMC to refine the chip design. The Tahiti XT2 will be able to facilitate significantly higher clock speeds, at significantly lower voltages, than the current breed of Tahiti XT chips.
Tahiti XT2, or Radeon HD 7970 GHz Edition, will ship with a core clock speed of 1100 MHz, 175 MHz faster than the HD 7970. The GPU core voltage of Tahiti XT2 will be lower, at 1.020V, compared to 1.175V of the Tahiti XT. It's unlikely that AMD will tinker with memory clock speed, since Tahiti already has a 384-bit wide GDDR5 memory interface, which gives it 264 GB/s memory bandwidth at 1375 MHz (5.50 GHz effective). According to the source, the new SKU enters mass-production next week. So best case, it should reach markets by late-June or early-July. '

if it's a complete respin on the core then it will definitely not be the same price - although it should have better OC potential too
if it trades blows more directly with 680 on stock settings, it will be similar to 680 on pricing as well

At least most.sites now are reporting similar specs, hopefully they will be in the right ballpark.
Sounds like we are looks ng at 1075/1100 core, and 5500/6000 memory speed. Lower default voltage meaning similar power consumption to vanilla 7970's.

Both of these cards will suit many gamers. One thing people seem to forget is, a lot of people buy GPU's/CPU's and never OC them. Many users on these forums don't. I see a few posts of users posting the stats and those stats are at the factory shipped spec.
People moan that the 680 is cheating in benches because of the boost clock. Poppycock is what I say. Regardless of what the cards are capable of, the stock speeds are what will interest many prospective buyers.
I started a thread a while back and asked, "do you bother with Overclocking?" Basically I was saying that no game as of then/now is capable of pushing my GPU to a speed where it needs an OC and I guess this is the same for the 7970. If you was running 3 monitors I could well imagine that every frame counts, so an OC is very important but for me on a 1080P, not so.
Anyways, back on topic, Both cards look good for the non overclocker
The main thing that irks me about the 670/680 is that you can pay £300+ for a video card and get a product that performs 5-10% worse out of the box than the next man who's paid exactly the same money for the same product.

it irks you that out of the box the vast majority if not all 670/680's are running higher than the stated specs on the box?

Had AMD launched this "proper" 7970 back in Dec/Jan, then we probably wouldn't had Nvidia pushing a mid-range card up to become a top-end card...
If both AMD and Nvidia take turns with this jabbing approach with higher core clock, then the future of GPU progression looks very grim...
I don't see the point with this after like six months...if anything, it's gonna lead to yet another range of poor bang for bucks cards for next gen, considering it is may be less than 6 months away.
Overall, the performance increase for this gen cards has been quite disappointing, but mostly it is because of the cards being more overpriced more than they should.

I don't think that's context it was implied andy.
He has a problem with the fact that without manually overclocking the 6's, he could buy one that isn't as 'fast' as the next guys stock 6, in regards to gregsters comments about users not overclocking.
It's in a similar fashion to SLI users who have one gpu faster than the other@stock speeds.
Gregsters point is valid, however, it seems but a distant memory to the cries along the lines of:
But the 580's a clocking monster, you pay extra, at stock speeds it's bit faster than a 6970, but when you overclock both of them, there is a bigger difference between them.
Now that's gone clean out the window and overclockings a thing of the past to half(figuratively speaking) of all the high end gpu users.
Problem being that the 79 series was on a new process, 6 months later, yields are better, it always works that way.
I think both have set their stalls out and that's what's going to be happening from now on, the desktop market is shrinking = less customer base = higher pricing for not much return.
Add in the 'gimping' of driver performance(not stability)imho from both teams that 'encourages' us to upgrade.

So,now the card is running at 1100MHZ instead of 1075MHZ, and with a lower voltage than the GPUs found in the current HD7970 cards.
It looks like performance per watt is going to improve quite a decent amount.
