Overclocking any CPU is piss easy these days.
In actual GPU news, looking more and more likely that the 290X is going to be 549 or less. Sapphire's MSRP *supposedly* is 499 (519 for the BF4 edition) even.
If true, that will most certainly cause some price shifts

Yep, 549 USD ;o
2 modes though and 95С, 55 Db и 325WT in max performance mode ;o

Noise is highly dependent on environment anyway. Looks like that Czech site tests on an open bench?
Power consumption, the heat that goes with it and noise are a bit disappointing though. Then again, the DirectCU2 cards are often cited as "relatively quiet" and they quite simply are not - unless you're cool with hitting throttling limits more often than not. My DCU2 isn't much more quiet than my reference 680 was, both are louder than my 5870 and 9800 GTX were, but neither is as loud as a 480. So meh, most sites put this thing somewhere around 680 levels in "quiet" mode, which is "quiet enough" for most people. Especially people who thought the 480 was "great" need to shut the hell up, as even in "uber" mode this one is not as noisy as the 480 was. Still a shame, they could've done better.
Performance is amazing though. At 1080p it sits between the 780 and Titan, go to higher resolutions and it generally beats Titan, often with ease. Well done AMD, well done.
Overclocking also seems good as far as the memory is concerned; most sites seem to get their core "only" just above 1100, but most also get the memory to 1500. That puts it at 384 GB/s bandwidth, that's not going to be a bottleneck at any point

I must say, I like AMD's concentration on heat versus performance and acoustics. Actually designing the entire chip and cooling system to run at a steady 95c is rather novel 
| Quote: |
I wanted to highlight our new PowerTune mechanism, as some of you have expressed concerns around acoustics and temperature. As noted in our explanation of the new mechanisms included in PowerTune on the 290 Series, we have designed the 290 Series to operate at a steady state of 95C. By running at 95C, we are both maximizing the performance and minimizing the acoustics of the product. We do this by increasing clocks/voltages and/or reducing the fan speed until the GPU runs at the temperature target. By having the GPU target at lower temperature, you sacrifice either performance or acoustics.
Some of you have expressed concern over the GPU running at 95C. Be assured, that 95C is a perfectly safe temperature at which the GPU can operate for its entire life. There is no technical reason to reduce the target temperature below 95C. However, like all aspects of PowerTune, this is completely within the control of the end user. If you would rather have you GPU operate at a lower temperature, such as 85C or 73C, we strongly encourage you to customize it to your preference and write about it in your review. This is, after all, the reason that we design products with this level of flexibility.

Sounds good on paper.

when do we expect this price drop to occur? If it happens that is.

There's no way Nvidia's keeping the 780 where it is (even though the absolute lowest in Germany may be 511, the average is still 550). I'd expect this to happen within the next few days. 770 will likely follow, that is still priced too high too, especially with the 290 lurking to come out next week.
I doubt they'll drop Titan, there's no point in dropping that one *that* much. With that they also still have the DP Compute performance, if they go cheaper then it becomes interesting for professionals instead of Tesla 
Nvidia's 780 Ti is also gonna have to run at 1 GHz or close to it on its base clock. The 1 extra SMX isn't gonna do much for performance, it'll be the clocks that determine if they can keep up.

Not sure if Nvidia is will be dropping their prices so easily. 280X and 770GTX are practically on par performanc-wise (depending on the specific test), still the 770GTX sits at over 310€ while the 280X can be had for around 250€ (in Germany).
"Enlightenment is man's emergence from his self-imposed nonage. Nonage is the inability to use one's own understanding without another's guidance. This nonage is self-imposed if its cause lies not in lack of understanding but in indecision and lack of courage to use one's own mind without another's guidance. Dare to know! (Sapere aude.) "Have the courage to use your own understanding," is therefore the motto of the enlightenment."

€310... €250... I payed €430 for the damn thing and not even THAT long ago.. 
Resale will be down the drain when i play to upgrade next year..

I think it's kinda similar to the 7970 with the temps and noise. Back then they chose to clock it conservatively by default to keep the temperatures and noise in check. If you wanted to unlock the full potential of the card you would overclock it and ramp up the fans.
Now they chose a high temp target by default and clocked it higher.
With my reference 7970, I had to get the fan going at 70% to keep the temps from going over 90 with my overclock, for example.

A review of the 290X, there's probably going to be a lot of websites posting tests like this today. |
Crossfire review vs the 780GTX.
http://www.guru3d.com/articles_pages/radeon_r9_290x_crossfire_vs_sli_review_benchmarks,1.html
(It's a bit louder during heavy load and it still gets very hot since it's targeting that 95 degree temperature limit.)
EDIT: Also Dice is talking about how EA's Frostbite 3 games will support Mantle.
http://forums.guru3d.com/showthread.php?t=382733
(Or rather they are claiming to have 15+ Frostbite 3 engine powered games that will support Mantle but I'm pretty sure EA earlier revealed that they had some 12+ games using Frostbite 3 in development so in total it seems most if not all of those will be given Mantle support.)

The 290X is getting praise on all fronts but the fan. Going to be really interesting to see what the third party vendors can churn out. Expect prices to drop the few coming weeks.

Good headphones that cancel outside noise are a perfect counter for such a thing, i defo don't mind a noisy fan

I tend to get the third party revisions anyway and those nearly always employ a custom cooling solution so if I do get a 290 GPU (EDIT: Which won't be anytime soon.) it'll be one of those models so temperature should be a bit better and noise might be somewhat lower though I like to run the GPU with manual fan speed at around 60 to 70 % anyways, noise doesn't bother me much, barely audible.
(The current Sapphire Vapor-X has been quite good, the 6970 lighting was also pretty good but it died due to a bad bios.)
EDIT: Getting a aftermarket cooler like the Accelero or adding a watercooling solution is also possible I assume, might already be some compatible units available for all I know.

Well, if you believe Thracks, the custom cooled solutions won't be about lowering temps under load, but about making the GPU run even faster.
| Quote: | The ASIC and product is designed at 95C so the GPU can extract maximum clockspeed out of the product's TDP. You don't want to reduce temperature, because that directly reduces clockspeeds.
What you want to do is raise the frequency that brings the board to a steady state 95C. That's what third-party coolers will accomplish. The greater the thermal dissipation capabilities of the cooling solution, the faster this card becomes.
People need to entirely rethink how temperatures work with this GPU, because it's not like any other product on the market. |

That 55% sounds about on par with my DCU2 really.
And yes JB, EK have already got their water blocks available so

Reading the hardocp review it seems that it is comparable to the 780 and a bit below the titan @ 1080p (but at -$100 than the 780, let alone the titan) but the strange part, for me at least, is that according to them it smokes both the 780 and titan at ~4K res 
What sorcery is this?

Nvidia have always done better (relatively speaking) at "low" resolutions.
And this time that effect is magnified by the bandwidth on the 290X. |
