Experience: 15 Months


Killer rates in OCLhashcat
First fan failing after 14 months
So I was initially really excited for a 7970 ebcause of their cost/performance ratio in October 2013. Had never gone for a card that didn't have a lifetime warranty. 14 months in the first fan stopped performing well. It's slow, noisey, and I even when thoroughly cleaned I can't reach the centre in an attempt to oil it. I'll have to use the three year warranty and get a replacement soon, hopefully I get the same model to keep the great hash rates.

Experience: 15 Days


low temperature and not noisy at all. Very good preform at 1440p
Cannot overclock.
It is a very good performer for 1440p. Pretty much can max out everything at 1440p. Its temperature under full load is very reasonable and it is not too noisy. However it cannot be overclocked. Stock speed is 1000MHz and increase it is to 1050MHz and video driver crash in desktop mode.

Experience: 6 Days


Super fast, good temps due to great cooler
A little loud under full load
Got this to replace a reference design 6950. So far it has been super fast and powerful but it does draw more power. At 100% GPU load using Furmark it is somewhat loud but otherwise it is a great card. The added games from AMD make this a no-brainer purchase.

Experience: 7 Months


Stays Cool
Voltage Locked (no overclocking)
Quite card that stays cool under load. Plays most games flawlessly at 1080p on high-very high settings. The 3 games you get from the Never Settle Radeon Gold Reward Bundle are an added bonus. Crysis 3 looks amazing.

Experience: 2 Months


triple fans, quiet up to about %60, factory overclocked, nice cooler design
No backplate
I upgraded to this card from crossfire 6970's and benchmark were showing that this card was equal to and sometimes faster than the crossfire solution. Very impressed with this card, it'll flex anything I throw at it.

Windforce cooler works awesome... keeps things cool without the added noise. It was cheap on sale.
It doesn't make breakfast.
Yes, it's voltage locked. However, I have read things saying that something in the neighborhood of 1150/1575 is still possible. But this is the internet, so take it with a grain of salt. I haven't bumped mine up that high yet, but even bumping up the core another 100MHz made ZERO impact on the core temps. At full utilization, it still doesn't break 60 degrees C, the fan speed has never gone above 63%, and the noise it makes is still barely noticeable.
All in all, I think the message here (and from other comments) is that it will OC some more out of the box, but don't expect godlike OC numbers.
For the price, it's probably one of the best bang for the buck deals on a 7970 you can find.
EDIT: Looks like my limit with this card might be somewhere in between 1125MHz and 1150MHz on the core. Still, 125MHz+ above the out-of-box core clock is not bad for a voltage locked card.

- Fast
- Cheap for a 7970
- Excellent Cooling
- Bios Switch
- Free Games
- Voltage Locked
- Bad Online RMA System & Customer Support
- Cheap Fans
- Loud While Maxed Out
I ordered through NC-X a just over a month ago. Tried overclocking, but with a voltage lock, I wasn't able to push it to where I needed it to go.

I flashed the secondary bios to make it think it was a Ghz addition(it's the same card). This gave me a higher overclocking ceiling but didn't unlock the voltage. My tests showed that the Ghz bios, even though I did get a higher overclock, I was getting worst performance. I switched back to default with a low 1050/1575 stable clock.

The last couple days I have been getting the wonderful sound of a 7970 fan bearing about to give randomly throughout the day. And today I have had the card go full RPM and lock the computer up when stand-by tries to enable.

I have submitted an RMA to Gigabyte about 7-8 days ago with no reply or permission to ship it to them for repairs. Also the online RMA system they have is very badly implemented. It doesn't give email updates and the RMA requests have to be accessed with a ref#. It;s like the request isn't directly tied to your account and they don't give you a confirmation E-mail to remind you what your "Waiting for Approval" reference number is.

Experience: 2 Months


Well built good cooling system
not so far
it's power full, it's quiet, you can run about anything with this.
This is my second Gigabyte graphic card and i really like their design

Experience: 2 Months


Voltage is locked
This video card is probably the video card i woud reccomand to any gamers who would like a high end gaming computer. It just run every games at ultra and 1080p. Althought i would't reccomand this card to overclocker maniacs since the voltage is locked

Experience: 1 Months


-Quieter than reference design
-Cooler than reference design
-Locked voltage (I can't undervolt my card :( )
-no memory voltage control either?
This is a great video card to own, it runs cool and using gigabytes OC guru software I have easily created my own fan curve to have it run around 65 degrees max while maintaining around 60% fan speed. As a result this video card has been way quieter than any stock solution from AMD or nvidia that I have tried in the past and runs cooler as well.
I understand why Gigabyte is locking the maximum voltage of the card but I really wish I had more control in reducing the voltage required. At the moment the voltage can be reduced if the GPU is underclocked at certain speeds and the voltage decreases are few and far between.
I have stressed tested this component for 7 days straight and it's a rock at stock speeds.
