Gigabyte has had an overclocked version of the Radeon HD 7770 graphics card for a couple months now, but the company is already readying a second revision of the card. Curiously, the new revision will maintain the same hardware but will run at slightly lower clock speeds. While the current revision (1.0) runs at 1100 MHz and 5000 MHz for the GPU core and memory respectively, the updated graphics card will run at 1050 MHz and 4500 MHz.
Beyond the lower clock speeds, the new revision of the GV-R7770 OC card maintains the same PCB, chips, and cooler design. That hardware includes a 28nm GPU, 1GB of GDDR5 memory on a 128-bit interface, and a PCI-E 3.0 expansion slot. Display outputs include a DVI port, full-size HDMI port, and two mini DisplayPorts. It also maintains the same custom Gigabyte heatsink and fan.
According to Videocardz, users will be able to identify which revision they are getting before handing over any money by looking at the box. Alternatively, users can identify which revision it is by looking at the sticker on the underside of the card just above the PCI-E connector. As a new revision, especially with the release of higher-binning chips from AMD, it is a bit confusing that the card is being released with lower clock speeds than its predecessor. It may be that the higher factory overclock was not stable on enough cards and Gigabyte was having to deal with too many returns – that’s only a guess though.
All the same, if you are shopping for a 7770 graphics card and have been considering the Gigabyte model, be sure to double check which revision you are getting.

Editor's Note: We are getting a lot of flak for posting this story today, telling us that we are "giving the site credibility", referring to the Pnosker site that first started the recall rumor, simply by posting about it on our site. Even though our post by Tim states to "take the leak with a grain of salt" and that "these GPUS go through rigorous testing and certification", some people think we were in the wrong to post about this.
So let me be perfectly clear - the recall referenced in the story below is almost assuredly complete and utter BULLSHIT.
According to Pnosker, NVIDIA is allegedly looking into recalling all Kepler based, 600-series graphics cards. Such a recall would affect users that have purchased GTX 670, GTX 680, and GTX 690 GPUs. The website has stated that their source has indicated that the graphics cards will possibly be recalled because the chips suffer from performance degradation after prolonged periods of heavy usage.
While their source has reportedly been correct in the past, the author cautions readers to take the leak with a grain of salt. Other websites that have picked up on this have mentioned that these GPUs go through rigorous testing and certification processes before getting to the market, so this rumor does not have much ground to stand on. Another reason to take this report with a shaker-full of salt is that if there was such a defect in the Kepler GPU, it would be more likely to completely fail rather than continue working with degraded performance.
This rumor is likely just that: a rumor. Why such a rumor was started is unknown but your Kepler graphics card purchases are probably safe from performance degradation, though they may not get as high of a boost clock as other users’ cards.
UPDATE @ 7:30pm ET: To quote from NVIDIA PR - "There is no truth to this rumor."

MSI today officially announced their new Radeon HD 7950 graphics cards with Twin Frozr III coolers. Specifically, the new cards are part of the "R7950 Twin Frozr 3GD5/OC" series. The new Twin Frozr III cooler features a nickel plated block, two 8mm Superpipes (heatpipes), and dual 80mm propeller blade fans that, according to MSI, delivers up to 10 degrees Celsius lower GPU temperatures versus reference coolers. Further, the dark gray Twin Frozr III cooler reduces noise by 13.7dB by using two slower spinning fans versus the single reference design fan spinning twice or more as fast. This extra bit of overclocking headroom has allowed MSI to claim a large "core and memory voltage potential providing up to 37.5% overclockability" Just like the company's motherboards, they are advertising the new graphics cards as being built with Hi-c CAP Super Ferrite Choke and solid capacitors that pass MIL-STD-810G testing. Based on the AMD 28nm Radeon HD 7950 reference design, the card supports the PCI Express 3.0 interface. Also, the card features 1 DVI, 1 HDMI, and two Mini-DisplayPort video outputs.
Further specifications include 3 GB of GDDR5 memory on a 384 bit bus, a core clock speed of 880 MHz, and memory clock of 5,200 MHz (effective, 1,300 MHz base). The card itself measures 261mm x 111mm x 38mm, (just under 10.3") which means that it should fit comfortably inside most Mid Tower (or larger) cases. While the 80 MHz increase in GPU clock speed over the reference design is not saying much, the cards themselves should have plenty of overclocking headroom beyond what MSI does at the factory. In our review of the AMD Radeon HD 7950 graphics card with reference cooler we achieved a nice 1050 MHz clock speed, and the "Supa-pipe" (as Josh likes to say) powered Twin Frozr III 7950 cards should be able to go even further beyond that, specific GPU permitting of course.
In addition to the new Twin Frozr III cooler powered cards, MSI is releasing a version of the Radeon 7950 with a reference design cooler and another Radeon 7970 card with a reference cooler to provide gamers with plenty of alternative options. Unfortunately, there is no word (yet) on pricing or availability. The Twin Frozr III version of the 7950 sure looks a lot cooler, so it will be interesting to see if it actually keeps the GPU cooler (heh).
