Most comparisons are using highly unoptimal settings for Hawaii; wrong BIOS and wrong clocks. An average 290X can manage 830 khash/s with about 170w, with settings concentrating on performance per watt.

Big Maxwell however, is likely to be superior to Hawaii.
170W R9 290X , without a huge undervolt I don't think so...

At stock a GTX 750 Ti gets ~260 kh/s

does it work in multi monotor setups yet?

Those aren't even out yet and even with mDP ports you would have a hard time fitting in the HDMI port on a singleslot output array.

Who said it has to be single slot?

Also hdmi 2.0 is finalized, as well as the dp 1.3 standard

Horrible title. AMD radeons are MAINLY for gaming. If you want to mine with them, that's fine by me. Miners are ruining the videocards market. Also, i bet that firepro's are better to mine than radeons.
I still don't see the profit in mining, in most places power consumption (cost) vs earnings are too close to each other

This would be great for a prodigy build if the card isn't too long.

why would this be a miners holy grail?

7950's are miners holy grail. Its about cost to performance and performance per watt. Currently the 7950's lead in this pack when it comes to mining.

surprisingly enough the new maxell cards do pretty good with mining.

That being said there is no way a dual gpu solution featuring 2 Hawaii cores is going to be air cooled. The 7990 or AMD's last attempt at a dual gpu solution was a mess when it came to thermals. Now they want to use a bigger and hotter gpu? Its definitely not going to be air cooled, if it even comes to market.

If I had to guess they will partner with asetek and provide a liquid cooling solution. Much like they have done with some of the FX processors bundles.

Because you can put 4 together and have 4x 290(X)s mining. This set-up is better than a 4x 7950 (and also 4x 7990) not only because it has more compute performance but because you don't have to spend for an extra mobo cpu ram etc.
