Amazing review Keep up the great work W1zzard!
This sheds some light on who the best dual gpu is and its the... 690... For almost the same price the 690 gets you better cooling and performance and looks nicer.

[overclocker!]

thank you for the review W1zzard!
As for the card what a piss off crap!!! I waited so long for nothing . i should've buy the 690 long time a go.....

[LAN_deRf_HA]

So less performance, more power consumption and noise vs the 690. Maybe it'll be $50 cheaper than a 690 but what nutcase is going to say $1050 is too much but $1000 isn't.

[Durvelle27]

just get 2x HD 7970 GHz editions and CFX would cost less and perform better

2x Stock HD 7970 vs GTX 690

I have an overheating problem with my gpu.
Is there any chance that the washers will make the card overheat less?

Why does it look like one of the 2 cores in a pic on page 4 fried?

give it a try, you dont even have to remove the cooler, so no problem with warranty. if you use metal washers don't accidentally short something on the card

you mean that? just some dust/paste residue and reflection of the camera

[Melvis]

Obviously needs better driver support that's a no brainer, in the games that do have good support it owns everything.

Very powerful card shame for poor driver support as most of the games it seem,s to be only using 1 core.

I see what your seeing but it looks like a reflection to me.

Shame about the issues with the cooler. That could be a VERY expensive design flaw. So much "premium" went into this card to have something that minor yet SO important slip thru.

Well I give Powercolor credit for stepping up the plate and doing a dual 7970 shame for the most part comes up short against the 690.

Powercolor is aware of the problem and they will look into it.

[Fluffmeister]

Hmm can't say I'm too impressed, especially for the money it costs.

The GTX 690 is clearly superior.

My bad

When I read it went nuclear (over 100°C) I only assumed the worst. Actually, kind of surprised it didn't catch fire. Guess you need it to quite a bit higher for that...

Good I would hope so. This is their "Premiere" card it needs to be "faultless" for the price.

Tahiti should have a thermal sensor- throttle the chip...

[W1zzard]

yes it will throttle the chip and when it still goes higher it will shut down the card

[moonlord]

This Devil can not take over GTX690, where is the true 7990?

[qubit]

So, the 690 is better. No surprise there. I'd really like to see a card on the AMD side properly trounce its competition from nvidia. We'd get so much more for our money then.

I wouldn't hold the heatsink mounting problem against it though. I'll bet it's just some stupid manufacturing fault where they simply used the wrong screws by mistake.

What other kind of washers could be use?

Ya Reminds me of the AMD XP boards in the day

IIRC AMD stated they arent making a Reference 7990, allowing the others to make their own designs. earlier News from this year here

Eh Its a QA issue, IIRC Card Heatsinks are still put on by hand, I could be wrong though...

[Lionheart]

My AMD fanboyish side would like to favor the HD7990 but I would still go with the GTX 690

Yes, that's basically the point I'm making. There's no way they'd make a dumb mistake like that by design.

[moonlord]

I'll never go for nvidia, i'm a real AMD fan, i want to see some competition.

[damric]

How did Zero Core work or not work with this card?

[EpicShweetness]

When it works it WORKS! However, I don't see it working very well. W.T.F I pay $1000 and get this . . . .

AMD doesn't make bad cards, arguably Nvidia brought the GK104 and GK107 (mobile chip) ,and doesn't have anything else. This is bold of Powercolor to bring the first duel 7xxx card to the table, but I'll leave it to AMD to do the engineering and see what they come up with.
