3 out of 5 eggsToo Much

Pros: This is one of the most powerful GPUs ever produced. I can run games like World of Warcraft and a highly modded Skyrim on high resolutions with steady frames per second. I had the Sapphire 7990 in my original system; but, sent it back because it was causing excessive overheating. The next Sapphire 7990 I recieved was defective and hardware itself continually failed. I sent it back again and it was replaced with this card; which, I must say is much better than than the Sapphire card as it actually has an HDMI port on the back rather than a DVI port and four apple mini ports (seriously?). I installed a push pull cooling system in my large open case, which has a watercooled CPU. If you feel some strange urge to try out this card, this is one of the more stable versions of it.

Cons: This thing runs at 105 degrees on idle, meaning you are just sitting there in windows reading a word document. When you slap on a video game in high rez, it will handle it, for awhile; but, the intense heat will cause the card to spuratically cut itself off, causing horrible frame stutters and may even freeze or crash the program. I've had this thing freeze my system just watching YouTube. It handles heat and frame pacing very badly. It is said that the frame pacing issue can be resolved with a driver update that won't be available till next summer; but, who is going to pay $1000 now for a card that is defective in it's current state? It stays roughly around 100 degrees Fahrenheit; but, it will get up to 140 degrees when running a game. This is when the fans kick in causing that loud distinctive whine that others are complaining about. This is why I installed extra internal fans to cool the GPU; but, if you have the time it would be better to water cool the GPUs cores. You would do better saving your money up to xfire to single GPUs together rather than running a single one of these flaky monsters.

Other Thoughts: It was the most powerful GPU until the Titan was released; creating immediate competition for this card and smothering it to death due to Nvidia producing a vastly more stable card than ATI's 7990. Anyone running demanding games on this card needs to either use frame limiting or vsync or you will turn your system into a pile of molten metal and silicon. Don't even think of xfiring two of these together. It should be noted that the 6 Gigs of graphics ram is actually 3gigs. You have to divide the ram between the two GPUs this card is composed of and still a lot of that ram isn't even active, so it's more like 2gigs. It was clear that AMD bit off more than they could chew when they came up with this, in some desperate attempt to jump the gun on the next gen GPU; but, I believe Nvidia curb stomped them at their own game with their latest product. I tend to buy ATI just because they are cheaper; but, they are not built as solid as Nvidia cards. So, in the end, you are getting what you pay for, except in this case, you are getting a thousand dollar heater for your home, not a beastly GPU.

4 out of 5 eggsSuperpowa

Pros: Handles everything no problem, achieved a score of 11442 on 3D Mark.
Looks beastly, just holding it gives you a sense of what you are about to experience.
Remains cool even under heavy load, maxes around 45c

Cons: Makes an incredibly annoying whine from the capacitors when not in use, like internet browsing. Worse for me because my case's design doesn't insulate sound well.
Powerjack, need I say more.

Other Thoughts: The powerjack isn't necessary but when you pay for this much the least they can do is throw in a quality piece of garbage you won't use.

3 out of 5 eggsIf you're over 25, read this

Pros: Nice card, monstrous, all metal, nice feel, and good construction. Pretty quiet for what it is and works about like you would expect it to.

Cons: Horrible, ear splitting coil whine at idle. I've had 2 of these now, the first being a Devil 13, and both sounded IDENTICAL. After using the card for 3 days I had ringing in my ears for the next 4. Some say you can fix this by forcing constant voltage, but this didn't work for my 2nd card, and I only found out about it after RMAing the first.

Other Thoughts: If you're older and can't hear high pitched sounds that well this should be fine for you. If you can hear it in the attached video, I'd recommend you find something else.

*The sound is accurate, video quality is only bad to save space.

5 out of 5 eggsFirst Day of Use

Pros: I was using Speccy and on idle it kept at around 35 c, though I didn't check it while gaming but am going to do that with fraps tonight.
Looks awesome
White LEDs on the bottom that light up on the GPUs when on.
Metal plate on the bottom blocking the gpu, looks cool

Cons: So long and massive it almost touches my hard drive bays of my Cooler Master HAF 932 Advanced, and takes up 3 PCI slots.

Other Thoughts: I have only used this since last night but it so outperformed my Geforce GTX 550ti that there was no comparison, also experienced no stuttering as some people exclaim.

5 out of 5 eggsGreat Card

Pros: The first one had bad memory so I had to rma which was really smooth through newegg. I got the replacement and works perfectly. Plenty fast. But boy it is a beast of a card. Barely fit in my full tower case.

Cons: It is a beast of a card so make sure you have a big enough case

4 out of 5 eggsGreat card but failed on me

Pros: - Relatively quiet cooler
- Extremely well-built and well-engineered w/back plate
- Neat activity LEDs behind each GPU
- Fast
- Crossfire on a stick

Cons: - A litttle bit too large vertically
- Fans can get loud under heavy load for longer period of time
- Failed after a few weeks

Other Thoughts: I used the card for a few days, as I didn't open and utilize it as soon as I got it. Played some games and the card performs as advertised. Borderlands 2 even with PhysX on low is returning me over 90fps on my high resolution 27" monitor, and other games I've tried worked great. I gave it a light overclock through Catalyst Control Center and everything was good. After a few days of use the card now exhibits a problem, where upon log-in to Windows 7, the display is corrupted with rainbow gradients. The card's GPUs never exceeded the low 70 celsius temperature during the whole time, so cooling isn't an issue. After trying it on three different motherboards with Catalyst drivers 13.8 beta, 13.8 WHQL, and 13.10 Beta it looks like the second GPU is toast. I can get the card working properly if I am lucky enough to get into the O/S and disable Crossfire, but that gives me a lot less performance. Unfortunately I am one day past my Newegg RMA period, as it is for invoice date, so I have to rely on Powercolor/TUL. I hope their service is as good as others have stated. This is disappointing because the "new" 7990 reference edition is unusable due to intensely loud coil whine, and this is a far nicer card in every way. The heat sink is a rugged metal, not plastic like that other edition.

5 out of 5 eggsBig and Beautiful!

Pros: -The cooling solution is great, stays cooler than other 7990 cards.
-Perfect for achieving tri-fire in conjunction with a 7970.
-boost button is a nice feature and makes overclocking simple.
-multiple output types, unlike most new 7990 cards.
-plenty of accessories, including a support bar.
-8 Free Games that you will actually want to play! Having issues getting the games, see below....
-My office owns Sapphire, MSI, Gigabyte, and Powercolor variations of the 7990, this cards is by far the coolest running.

Cons: -can get loud, but not loader than my gaming volume!
-support bar is of limited use, not sturdy, but ok if it fits your case layout.
-(a pro for me)this card is huge, so proceed with caution if you have need for your central PCIe slots.
-voltage is locked on the card I received, and I believe it is done through hardware.
-this is a 7970 x2 solution, not a AMD Malta. While it runs cooler, it also has lower clocks.

Other Thoughts: Be sure to download the latest BETA drivers from AMD, currently 13.8beta2.
Any issues with the free games promo should be addressed directly with AMD at

2 out of 5 eggsCrossfire broken

Pros: Solid made,
good performance when working.

Cons: crossfire not working with most of the games, meaning you are getting a 7970 basically. It will crash your games!

Other Thoughts: The supposedly best card turned out to be such a disappointment, this will be my last AMD card. If you must buy this card, don't buy the ones with replacement only return policy.

4 out of 5 eggsGood card for the money, with some minor drawbacks

Pros: These are Two Radeon 7970 cards combined into a single graphics card. Gaming performance is increased by using crossfire. They also work nicely in Linux for mining Litecoins, etc.

Cons: The fans have very flimsy blades, I broke two fan blades with my finger alone while tinkering with the card. This is totally not acceptable.

The 7970 chips used in the car do not look like they are binned are produce a lot of heat.

One of my cards failed, but was promtly RMAd by the nice folks at Powercolor.

Other Thoughts: Takes up 3 slots and 3 PCIE power cables.

5 out of 5 eggsBest buy of possibly the year

Pros: I got two of these cards each about $600 dollars. Reading other reviews about the two year warranty made me question, however on receiving the card I have observed it is nothing but quality capacitors and sturdy construction. I can now max games for at least the next 5 or 6 years!!! If not more. Buy them now because AMD is no longer producing these monsters and they WILL sell out.

Cons: The price is the biggest con. As of today they went up to $850.... Not sure why they did however, If they drop the price to $650... BUY AT LEAST 1

Other Thoughts: AMD has new beta drivers that reduce microstudder tremendously. It is worth it to buy these cards, i have put in more than 2 months research into building my rig... If you want physx, download the software from nvidia's website. And remember always download the drivers from AMD's website; do not use the CD unless you have no choice.
