Don't you think that calling this card a 6gb edition is a bit like saying my car is a "5 wheel edition"? Not that it is just AMD that does this... just, it perplexes me that they can do that.

As I understand it, it's more like looking at yourself in a mirror and saying that there are two people in the room...
The power in use is a worry 500+ watts got to be highest ive ever seen, Considering 2 680s in sli use below 500 watts system draw. To see 1 card with 2 gpus pulling that level is just insane.
Crossfire drivers are not working well with this card its slower in certain tests than the 7970.
I wonder why its been released so late in the day as anyone surely wanting a duel gpu has long since brought a 690.

Yes, that is exactly why they did it, because no hardware company has ever knowingly pushed out an unsupported pile of crap onto consumers.
Far more likely the reason we haven't seen an official HD7990 can be seen in the Load power figure on Page 8.
Also, why waste the engineering resources on a card that will attract few sales and lots of criticism (high power consumption and poor scaling)? AMD wouldn't make back what they expended in resources. If it was a convincing winner against the GTX690, then maybe...

yeh they are the same. even the cooler is the same, just without the red bits. there is a different '7990' in the HIS Radeon HD 7970 X2 IceQ. i did see a review somewhere comparing the 2 but i can't find it now. from what i remember the devil 13 had better results but drank more juice.
I've used the 9000GX2 and 3850X2 one was much better than the other but neither were perfect - I honestly thought we'd see any multi-gpu compatability issues resolved by now - I guess Lucid Logix has shown us how hard that can be, it probably means it will always suffer unless it's truly embraced or dropped by the manufacturers.
From what I can deduce, driver support becomes more flakey over a (relatively short) period of time, the micro-stuttering, the lacklustre power useage under load (increasingly important given the non-stop rise in energy costs)....current driver support even failing to deliver consistent performance across games - there's very little to like.
I don't want to start a green vesus red debate here - but I was always given to understand that Nvidia's multi gpu cards were less volatile than AMD's in the long run?

In the games we test, it's drivers are certainly far better, offering better scaling and more reliable results.
Yeah and that is very tempting. But I was thinking mainly that the 690 uses less power so I wouldn't need a new PSU. And I also would have difficulty accepting the fact that after spending 700 ish quids on something so uber, it still doesn't let me turn on the pretty physx smoke and stuff in games like Arkham City :/
Third world problems I know. :P

I have never had one in my life, but I have one in my basket at Scan at the moment and am dicing on pulling the trigger. The only reason is that I am upgrading to a very high resolution 27" monitor and the single slot cards all struggle with that resolution :(
Again... third world problems :P But for me the 700 ish pounds is a huge amount of money for me so I would have to consider a lot and fuss about everything before deciding. Nice to have some choice though at least.

You should be able to, I play it with full detail and PhysX on a single 560TI. You should at least be able to use one of the GPU's for graphics and the other for Physx

That'd be me! Ha, I actually didn't, although now it's bugging me that they're not all aligned the same way D:
Ha ha. Yes. That is a very suitable analogy

Okay, okay... I'll leave...
no, but really? and Intel are talking 10w CPU's...
Yes. A 5770 can play Crysis 3, so I'll hazard a guess that this one won't run in to too many framerate issues.
Unless the driver isn't written well enough.
I'm sure they'll manage it for AAA games ;)

Edit, ahh I see you meant the 7990
