Power draw, thermal performance, and acoustic output should all be important factors to consider as you choose between different variations on the same graphics processor.
In order to gauge power use, we used a Kill A Watt meter at the wall during our Battlefield 3 testing.

The blue bars represent idle power consumption compared to a Radeon HD 5450, the green bars reflect power consumption under load, and the black bars indicate peak overclocked power use.
Each step of the way, our results reflect clock rates and voltage settings, yielding little in the way of surprises.
Our thermal measurements were also taken during Battlefield 3 testing and logged with GPU-Z and MSI's Afterburner utility.

The temperature differences between these cards compared to ambient is fairly similar overall. Zotac's offering is the outlier, perhaps as a direct result of the highest default voltage setting. We would have expected those numbers to even out once we overvolted the other cards to similar levels, however, that's not the case, and Zotac's thermal reading remains significantly higher. In contrast, MSI’s Twin Frozr II performs well here.

Keep your eye on the green bars, as those represent acoustics using stock fan settings under load. Asus leads just slightly by virtue of its quieter idle noise level. Four of the cards give us the exact same load reading, though, which is pretty impressive given the range of different cooling implementations. Zotac's card again returns louder-than-anticipated results as its fans push to keep those higher thermal readings down.

This dosent match with the above chart
Your kidding right, my overclocked 580GTX at 60% fan speed idles at 32c. Cards down clock themselves which allows them to run cooler at idle temps even if it were clocked at upwards i don't think a card would get hot unless it was being used.
I have the feeling that even a i5 2500k@4ghz bottlenecks a 7970 @1080p in most newer games.
If the GPU market goes the way it does, it won't take long that even midrange cards will be bottlenecked @1080p by the cpu.
Not really. This is mostly game depended. Depends on how much stress each graphics engine push at cpu and gpu.
Games like Dragon Age 2 and SWTOR are gpu intensive. So a GTX570 (that I have) is being used at 1080p at 99% of its usage with a low performance nowadays Q6600 in SWTOR (used MSI after burner to monitor it).
But with games such Skyrim which cpu is more important than other games, a highly clocked sandybridge is required in order to play smoothly at 1080p.
One thing is certain for sure. The higher the resolution the more gpu power and less cpu power requires a game.
The 280 idles higher than the 580 to the best of my knowledge, plus it's a 65nm part and the largest gaming GPU ever created.
That's an enormous amount of fan speed for an Idle GPU. Hope you're happy having a nice loud fan at idle. I can't imagine how loud it gets under a light load.
To the article, I don't think these comparisons are really necessary. All the cards are going to have different overclocking capabilities, which is what anyone from tom's is going to check. Hell, the worst card you guys test according to this comparison might overclock the most, and be the best card for the money on someone else's comparison.
For a $30 savings the ASUS ENGTX560 DCII OC/2DI is worth a look. Sure if you run the fans at 100% a higher CFM fan is going to be very loud, but no one runs their fans @ 100% either.
With Apps like MSI Afterburner and others it's incredibly easy to OC any GPU. It's a balancing act between performance, temperatures, and dDA (noise). One of the big reasons for water blocks on higher end cards, etc.
BTW - I appreciate the Article, it's enlightening and offers good info. Thanks!
Quite right! Fixed.
The GTX 560 is comparable to the 6870, though generally thought to be a little slower but with better OC headroom. The 6950 is much faster, and is comparable to the GTX 560 Ti.
