To my point, and sorry for the double post:http://www.tomshardware.com/reviews/radeon-r9-280x-third-party-round-up,3655.htmlPage 12This operates on the assertion that the Toxic cooler for the 280x is quite similar to the 290x Tri-x, but that is conjecture. I'm sure there are subtle differences (though maybe those make all the difference in the case of the 290x).Page 6Subjectively the Asus sounds quietest to me in terms of the kind of noise it produces.Page 4,5Toxic is a good 8db louder as measured (and almost the loudest) but middle of the pack in relation to all the cards with regards to temps, and slightly cooler in temps than DCII and windforce by a few degrees.Page 2The Toxic is about 7% higher in clocks.The differences in the 290x are much more pronounced with the DCII and windforce losing in both aspects of temperature and noise. The open bench tests were more similar to the 280x tests which I assume were open bench, but the DCII and WF still came out ahead in terms of noise even in that test. Sapphire must really have reworked their Toxic cooler or this is a new design we didn't see on the 280x cards.
