AMD Radeon R9 290X Correction
Ultimately, any piece of equipment can fail, and this is what happened to our current clamp while we were benchmarking the Radeon R9 290X. That means some of the power consumption results in our launch article weren't quite right. Power was one of the last things we measured, and not only are the Radeon R9 290X’s numbers for the gaming loop too low, but the error got worse with time, increasingly throwing off the curve. Thus, we're repeating our readings on the 290X and presenting the corrected curve below. Also, we've taken steps so this doesn't happen again, using additional equipment and comparing the results through different methods.
On the bright side, the Radeon R9 290X we're using for our new power consumption benchmark isn’t a press sample sent to us by AMD, but an off-the-shelf retail card.

Power Consumption Overview for All Graphics Cards
Here are the power consumption numbers for all of the benchmarked graphics cards, including the corrected Radeon R9 290X results.





Bottom Line
Once again, the Radeon R9 290X’s power consumption at idle is very high, and it gets a lot worse when a second or third monitor is connected. The Blu-ray playback results are also far from satisfactory. Things get a lot better when it comes to gaming loops, where the Radeon R9 290X is much improved over AMD’s Tahiti. This lets it gain a lot of ground on the more efficient Nvidia graphics cards. Seeing that the gap is really not that large any more, what remains might eventually even be eliminated completely with performance increases due to driver optimizations.

Chris, these results differ drastically from real world results from 290X owners at OCN... I understand that your observations are anecdotal and based on a very small sample size but do you mind looking into this matter further because putting such a statement in bold in the conclusion even though it contradicts real world experiences of owners just provides a false assumption to the uninformed reader...
The above claim has already escalated further than it should... A Swiss site actually has already rebutted by testing their own press sample with a retail model and concluded the following:
In the quiet mode, where the dynamic frequencies to work overtime, the situation becomes slightly turbid. A minor performance difference can be seen in some titles, and even if it is not about considerable variations, the trend is clear. In the end, it does an average variance tion of only a few percent, ie no extreme levels. The reason may include slightly less contact with the cooler, or simply easy changing ambient temperature.

Now to wait for the non-reference cards at the end of the month!
It looks like a good card for the price as it even keeps up with the $100 more GTX780. This is good as NVidia may drop prices even more which means we could also see a price drop on the 290X and I wouldn't mind a new 290X Toxic for sub $500.
Best to wait a month or two before buying to see how this all goes down
Some people who need CUDA for work and GPU for gaming will still get 780s, but no one will get 290x for $150 premium just to get a couple more FPS over 290. AMD just shot themselves in the foot before hurting nvidia.
Nvidia made a very good job with the reference cooler(but you really pay for it)... do you think AMD could not have pulled of a "monster" cooler?? is it really hard to make a good cooler? no, it is expensive.
You could do this, you have youre sources
Strange thing and I know some of us were going through this. I was thinking getting a 280x on Black Friday/Cyber Monday but the price tag is leaving me with something to think about. I think I'm just going to save up the few pennies to get something I thought was out of my price range ($300-450) a month ago ($650+).
