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

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

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.

5 out of 5 eggsGreat value per dollar.

Pros: -Price was finally right(I got mine for 590 after rebate)
-Card gets excellent power delivery from 3 8-pin connectors
-Card runs exceptionally cool at stock, not a hair over 59-60c per core when both cores are at a full load
-Dual BIOS
-Game coupon
-VOLTAGE UNLOCKED(at least mine is)
-Decent accessories
-pushes 50-80 FPS in Crysis 3 @ 2560x1440, x16 AF, FXAA, dips in graphically intense areas though such as the first rain mission

Overall if you have a single 7970 and want to upgrade to a beastly single card solution the 7990s are a good path to take but I would still hold out for a little while to see if they drop anymore. 650 would be the most I would pay for a 7990.

Cons: Not many, it is triple slot and it is long. I have a Coolermaster HAF XB though so this is not an issue nor do I need that weird power jack thing.

Other Thoughts: My card's core overclock topped out at 1125 mhz. I just want to stress an important thing I found when trying to overclock. When I first installed the card I enabled the second "boost" BIOS which is when you press the red button on the back in. I was not able to overclock at all nor were my voltage changes applying effectively even though Afterburner read higher voltages, I do not believe that the specified power was being delivered. I would instantly crash before I loaded into a game such as Crysis 3 before seeing the graphics and thought that my PSU was limiting the potential. I depressed the red boost button and rebooted and now I'm actually able to overclock this like a normal video card(increasing core increments of 25 mhz, waiting for crash, boosting voltage, rinse repeat).

5 out of 5 eggsdead after a month UPDATE

Pros: I feel a blush of shameful irony here, ranking my tech knowledge one lonely egg shy of a full basket, yet being incapable of discovering a means by which I can edit my preceding one egg warning review. Tech savvy overstatement not withstanding, Powercolor not only sent my replacement with respectable haste (2 weeks for general acknowledgment that indeed card was bad &, most relieving, another 3-5 days for the completion of my RMA procedure with a brand new replacement unit shipped forth) but did so with nary a word of complaint that, as I had installed an EK waterblock on the device, was lacking several of the identical match original screws in packaging the return unit as well as the clear as day fact I returned my 7990 with utterly different thermal pads, thermal paste, and likely various other nuisances that would have no relevant impact on the card's function and,therefore, no baring on the status of said RMA claim. Nevertheless, I was worried that, perhaps, a company with less top to bottom integrity would seize any excuse to shirk responsibility. With this experience, I hold Powercolor in high esteem; having owned a 6970 device (running strong in my best bud's machine) with custom HSF that has thus been flawless and well designed and now the original pre-Malta 7990 "grand-daddy of them all" that though did break and require RMA, said replacement runs faster than the slimmer & more intensely binned AMD variant and, when stripped of the various shrouds, it requires only 2 eggs worth of tech knowledge to realize which device is better engineered, which card operates with a cleaner & stronger power draw, which has the greater clock-speed potential, which has the better heatsink & fans, et al. A quick point to those ready to dispute my claims on the heatsink claim and, perhaps, clock potential: just because AMD meticulously binned these Tahiti chips & selected in effect the absolute premiums for their offiical 7990 & thus, on average, have cards with less voltage @ equal clocks comparatively, doesn't mean the engineering details & component selection of the PCBs aren't vastly superior in favor of Powercolor. My 7990 has a solid 76/74% ASIC quality rating, and I can chop voltage immensely whilst preferring a fan curve nearly inaudible whilst dancing around 80° celsius. The VRM temperatures could be confused with cucumber cultivation, that's how cool they run, like a snowman in the boston marathon.

Anyway, I have re-established my EK block and this 7990 clocks 1150/1850 without eclipsing 55° whilst sharing a toasty section of water-loop & radiator with an MSI Lightning 7970.Radeonpro keeps it smooth, and I look forward to the crossfire rectification driver. Powercolor is a great , great company & this 7990 was a well-invested device.

Cons: Frankly, crossfire on a stick has always had it's detractors; from cost, to absolute in tandem clock-speeds, and even potential issues with bandwidth bottlenecks from shared PCI-E lanes for two assuredly bandwidth intensive GPUs. This argument ignores the almost embarrasingly high bandwidth interconnect dual GPU devices are found connected via, the 48-lane PLX bridge now updated to 3.0 version of the pci-express interface. Yep, you get PCI-E 3.0 transfers between each chip even on old platforms, from x58 to z77 or whatever. Secondarily, this huge bandwidth link provides GPU to GPU bandwidth that simply dwarfs any motherboard based link as well the crossfire bridge transfer protocol, the current preferred transfer method for final frames rendered by each GPU and how they are shared. GPU to GPU bandwidth is underrated something awful, as synchronicity betweened finished frames and the more refined and perfected this syncronization is will eventually shift crossfire & SLI's end-user experience to virtually identical to that of a a single-gpu smoothness, only twice as powerful. Simple concept, duff-ravaging difficulty in practice.

Other Thoughts: Thanks, Powercolor. Malta is for shakes at A&W, I'll take my O.G. unoffiical New Zealand.

5 out of 5 eggsThis Card Scares Me

Pros: Oh wow this card is huge , all the videos and feed back do not prepare you fully for when you hold it in your hands , and it gets beast performance once you figure everything out runs wow 40 man raids on ultra with 3 monitor eyefinity and no lag so it should have no problem with shooter games or anything else you care to throw at it stock with the turbo button pressed and no further oc

Cons: well what`s a review without some constructive criticism ? first as seen in the video to the devil 13 respectively , the first thing you should do is throw the disc in the garbage unless your like me and keep it all for whatever reason , do not go to powercolor site ! go straight to amd and get the most recent drivers and catalyst software , then do not forget to go to hardware/device mgr. and update the second gpu driver failure to do so will cause sloppy performance and failed benchmark scores , when you install catalyst it only installs the main driver not the secondary but once you follow up and make sure you have both drivers updated then it will change your gaming life ! the power jack is not userfriendly nor does it really work at all if you are using this enormous card in one of the lower slots as i must so i can still use my tv tuner card , there was no way to adjust this so it would fit it is way too tall or way too short no matter how you try to put the pieces together so epic fail in that department , as long as you use screws in all 3 slots and have a descent motherboard such as asus sabertooth 990 fx r2.0 or equiv. you should have no problem supporting this card , after awhile i did figure out how the jack works but only to find out that with this card in the third slot there was no way i could get it in there so it is doomed to a box forever . it does make a nice conversation pc though

Other Thoughts: see my review on xigmatek elysium case for specs

5 out of 5 eggsAmazing!!!

Pros: VERY VERY VERY FAST GPU!!! Have this card with the AMD FX 8150. This thing plays newer games at 60 fps+ on max settings. I'm playing Crysis 3 @ 1080p on max settings with AA at medium and I average around 65-75 fps during large maps. I'm sure with newer drivers this thing will only get faster!

Cons: pricey! power jack is kinda lame but does the job.

Other Thoughts: I'm really hoping Adobe releases the OpenCL patch for Premiere and all OpenCL accelerated programs soon for Windows because I can't wait to see how this thing handles 4k playback!

5 out of 5 eggsAmazing

Pros: Easy install and drivers were no problem. This was one large card and performs just as large. Bought it here last month cost a lot of hard earned money. I purchased the 7990 to replace two 5970's I have been running for the last two years. The 7990 out performs both of those cards by a large percent. I'am getting 65 to 74 FPS on BF3 everything at Ultra with out any OCing. Thats with 3 X 27in Samsung SyncMaster monitors 5760 by 1080 res. Temps are good and fans only rev up while playing keeping the cards about 68 to low 70's. Must say I have no regrets as I like single card over duels any day.

Cons: Only con and its not a big deal is the power jack. It is not that easy to set up to hold the weight of the card which is a lot. They could of spent a few dollars making a more sturdy one.
