Secondly ZOTAC isn't a bad company for GPUs in my experience. I had a GT 430 brand new that is still running 3 years later. (fanless version) I think people just have different experiences with different companies.

I'll give you that.

Haha, wood screws...
Does this still use less power than a 480?
I remember 480s used more than 5970s, and this gen is much more power efficient than last, so i wouldn't be surprised if a 480 used more.

How can it be slower than a 7970 GHZ Edition in games like Skyrim???? I'm really surprised.thumbsdownsmileyanim.gif

Everyone knows that is much better to get 2 7970's or even better 2 7950's for less money, with higher overclocking,quieter and guaranteed CF scaling right?

The 6990 was a great card and it was really worth manufacturing imo but the 7990 just seems like a waste of time tbh.Too much heat and too expensive compared to other setups.

It seems about on par with the 690 at normal resolutions. I want to see what it does in comparison to a 690 on triple 2560x1600.

the specific card which TPU reviewed seems to be a faulty one. would not consider this review correct.

http://www.techpowerup.com/reviews/Powercolor/HD_7990_Devil_13/

"All data in this review was obtained after I repaired a major design error of the card. When I received it, the card ran extremely high temperatures, reaching beyond 100°C, causing instability and black screen hangs. The fan would also run at 100% almost instantly. This is caused by screws with integrated stop that resulted in too little mounting pressure between GPU and heatsink, clearly an engineering oversight. I added three metal washers on each screw by removing the screws, adding the washers and putting the screws back. The cooler was removed for this procedure, and thermal paste was replaced with a thin layer. Only this procedure enabled the card to run stable. The card was unusable out of the box."

hardwareheaven has got a review of the same card. it performs brilliantly.

http://www.hardwareheaven.com/reviews/1561/pg6/powercolor-devil-13-hd-7990-graphics-card-review-battlefield-3.html

the TPU review showed the BF3 scores lower than a single HD 7970 Ghz for the powercolor HD 7990 at 2560 x 1600 and 5760 x 1080. thats more a card problem. HD 7970 CF plays very well on BF3 with excellent scaling.

Not necessarily the card is at fault here.
They were using different drivers.

I would rather get 2 7970's or 2 680's/670's imo. I have never been a fan of dual gpu cards ,especially when they have 3 8 pins LOL. Plus overclocking will simply be better with 2 separate cares and the cards wont have to share a slot.
