Price performance ratio is incredible, but I will definitely wait for cards with an aftermarket cooling solutions. The heat and noise from the stock cooler do not look like they would be something I'd want to put with. Once again, AMD is that close to having something special, and some how manages to screw it up. Let's see what the board makers come up with.
From the THG review:
http://www.tomshardware.com/reviews/radeon-r9-290x-hawaii-review,3650.html
"We decided to forgo the video demonstrating what a 95% duty cycle sounds like. It’s pointless and potentially bad for your long-term hearing. The noise is simply unbearable without commercial-grade ear protection."
"The 225 W we measured using a compute-heavy load and stock settings can be pushed as high as 295 W by giving the fan more room to spin up and targeting a lower thermal ceiling. Unfortunately, those conditions don't last. Once the Radeon R9 290X hits its target temperature, power consumption drops considerably. This explains the card’s relatively low performance in our GPGPU benchmarks."
"AMD says it gives you total control over this and, thanks to an updated PowerTune technology that defines maximum fan speed (rather than dialing in an absolute value), indeed it does. But you also get stuck with the same noisy thermal solution that makes reference Radeon HD 7970s so acoustically grating. Company engineers insulate you from having the same loud experience by implementing two firmware modes: Quiet and Uber. Quiet keeps the fan under 40% duty cycle. Uber lets it get up to 55%, and that’s too loud for me. So, I stick with Quiet mode. Once Hawaii is at 95 °C and the fan hits 40%, frequencies start retreating quickly. It’s not uncommon to see them bouncing between mid-700 to mid-800 MHz in single-card configs. In CrossFire, they’ll drop to 727 MHz and stay there. The bummer is that a more effective thermal solution could keep acoustics down and allow Hawaii to operate toward the top of its range more consistently."
As someone else mentioned, this looks like an engineering train wreck.
It's actually the opposite, reversal of 7970 situation. A lot of engineering work went into it competing with the 780 and Titan with a smaller die. They've tapped a lot more of the chips top performance with the reference GPU. 290X is going to need high end custom air or water cooling to extract any more out of it.
