Customer Reviews: Sapphire 21197-00-40G HD 7970 Graphics Card (3GB, GDDR5, DVI-I to VGA Converter)
Amazing card for its price, it beats the 680 from NVIDIA anyday - both price and performance.
Able to use Sapphire's own Trixx to OC to 1200/1700 at 1.3 voltage, or 1125/1650 at default voltage. About 20-30% faster than my 5970, runs MUCH cooler, and has no microstuttering/x-fire driver issues to worry about. After being OC'ed, this card is approximately the performance of a 6990 and neck to neck with a 680 with 1 gig more ram to play with. AMD also has better multimonitor support and arguably better 2D picture quality.
Default voltage temps runs about 60 with load and 36 idle, 1.3 voltage runs about 70/45. However, even at 70% fan speed, it's only borderline bothersome and the fan speeds never gets to annoying levels at default voltage and automatic fan speeds.
Contrast to what some people say, the fan is pretty sturdy. It stays on the video card tightly and never wobbles or worries me. Overall, card has a high build quality feel to it.

Great bit of kit if a little overpriced on initial release, ideal for multimonitor set up and the 3GB of VRAM will keep this bad boy going for years to come. Get one now! (Fit's inside a Fractal Design Refine R3 no problems)The card is near silent in my case and cannot be heard over the case fans even when under load.
BF3/Skyrim/SwtoR all play at max.
Received the card the other day and have installed it. What a little beauty!
No issues straight out the box, and software is pretty good and self explanatory. May have to start playing with the OC software at some point, however that is what popped my old card :( but on the plus, reading the review on the Tech Radar site where they have played with the OC they managed to reach the limit of the GPU and memory clock speeds without going above the hardware capabilities and running the Windows Experience Index it is hitting the 7.9 anyway.
Only minor downfall with this is there is no back plate, so make sure you keep those wires and connectors tied back!
I had 2 6970's running xfire before I bought this beauty. I was not happy with the performance of xfire, so I bought a single card. As soon as you put it in and turn on the computer you notice....Nothing thats right no heat coming out the back and no noise, If you had owned the 6970 you'd think the card you just bought was broken.
Anyway, these are the important bits
Up to 925MHz Engine Clock
3GB GDDR5 Memory
1375MHz Memory Clock
So 5 min later I have clocked it too 1000MHz Engine and 1500MHz Memory by using AMD std overdrive, no need for voltage changes.
A quick Demo using furmark,
BEFORE ANY TESTING
GPU Clock 300MHz
Memory 150 Mhz
Temp 28 Degrees C
Fan Speed 20.0%
GPU Usage 0%
Now Furmark High Settings xTreme Burn test
GPU Clock 1000MHz
Memory 1500 Mhz
Temp 70 Degrees C
Fan Speed 33.0%
GPU Usage 100%
When I ran the same test on the 6970 it hit a whopping 93 Degrees C with a fan speed of around 75%
This card is better, super quiet and runs way cooler
