There are some people disappointed with it, guess it all depends on the expectations.
Considering that it is a new architecture and running with green drivers, it is a decent performance.
Noise under load could be better, though.

AMD to launch three Radeon HD 7000 chips by March
...
We got hold of some fuzzy release dates for the Radeon HD 7000 generation that in total has three different chips.
The first one to be officially announced, Tahiti XT, ended up with the Radeon HD7970 designation and we won’t go over the specs since it has the talk of town. This flagship model should start shipping on January 9th along with the Radeon HD 7950, Tahiti Pro card. We can confirm that Tahiti Pro has a 900MHz GPU clock, 1792 shaders, 112 texture units, 32 ROPs as well as 1250 GDDR MHz memory, 5GHz effective. It comes with 3GB memory and $449 suggested retail price.
It already looks like a very interesting card, but an even more tempting version is on the way. A Tahiti Pro variant with 1.5GHz memory will show by March, under the same Radeon HD 7950 brand.
Pitcairn is yet another codename that will cover the Radeon HD 78x0 series and HD 7870 and 7850 should launch in February. This is a 245 square millimeter chip and cards based on it will cost between $299 for the HD 7870 and $219 for the HD 7850 with 1GB of memory.
Cape Verde is Radeon HD 7770, a 164 square millimeter chip with 896 stream processors, 56 texture units and 16 ROPs. It should start selling in February for $149, while the HD 7750 should end up even cheaper but penalized with slightly lower clocks.
All these cards are expected by March and some LE editions of Tahiti and Pitcairn should show up in Q2 2012. It looks like AMD will have a very strong portfolio in 2012. What’s more, the most interesting cards, such as Pitcairn, should appear in about two months, well ahead of the competition.

AMD's Radeon HD 7970 graphics processor
We've spent the holidays on the Southern Islands
...
For several generations now, whenever a new Radeon GPU was making its debut, I have bugged AMD Graphics CTO Eric Demers about whatever features were missing compared to the competition. There have always been feature deficits, whether it be graphics-oriented capabilities like coverage sampled antialiasing and faster geometry processing or compute-focused capabilities like better scheduling, caching, and ECC protection. Each time, Demers has answered my questions about what's missing with quiet confidence, preaching the gospel of making the correct tradeoffs in each successive generation of products without compromising on architectural efficiency or time-to-market.
That confidence has seemed increasingly well founded as the years have progressed, in part because we often seem to be comparing what AMD is doing right now to what Nvidia will presumably be doing later. After all, AMD has been first to market with revamped GPU architectures based on new process tech for quite a few generations in a row. It hasn't hurt that, since the introduction of the Radeon HD 4800 series, AMD has been at least competitive with Nvidia's flagship chips in contemporary games, if not outright faster, while building substantially smaller, more efficient GPUs. Meanwhile, the firm has steadily ratcheted up the graphics- and compute-focused features in its new chips, gaining ground on Nvidia seemingly every step of the way.

XFX’s Radeon HD 7970 Black Edition Double Dissipation: The First Semi-Custom 7970
... AMD has loosened the leash on their partners just a bit, and as a result we’re seeing semi-custom cards planned for launch earlier than usual. XFX looks to be the first partner to take advantage of this more liberal policy, as alongside the reference cards being launched today they’re launching their first semi-custom 7970s

Radeon HD 7950 comes on January 31st
...
In case you somehow missed it, the Radeon HD 7950 features 1792 stream processors, or 28 GCN compute units, and a 384-bit memory interface paired up with 3GB of GDDR5 memory.

AMD Radeon HD 7970 Overclocking Performance Review
We overclock the Radeon HD 7970 in Overdrive and show you what 1.125GHz of performance looks like. Then, we go to the edge and overclock the voltage and take this GPU past 1.2GHz for stellar overclocked gaming performance. We compare this to an overclocked GeForce GTX 580 and see how performance stacks up.
