I Purchased in bulk Sapphire R9 290 and 290x Tri-x's.   These cards run incredibly quite and cool compared to others.

My 290 Tri-x in one rig is running without any external fans on it at 65c and 840 k/hs (not pushing it very hard)  was up to 880-90 when pushed higher.

The 290 Tri-x is $475 and the 290x are $675 Each, so far have only gotten it up to 940 out of the box.  Have not tweaked it yet, if anyone has a configuration they would like to share please text to me and I will display the results on screen shot.

I also have 4 Sapphire R9 290x cards for $600 each, they are being run right now in a rig that I am switching out for these Tri-x cards.  Original boxes and receipt ($650 each) from Bh Photo to cover the warranty should anything happen.  5 MSI R9 290x available as well for $600.

This is the bulk order price which is $25 cheaper than Newegg.  I would ask that you be responsible for shipping for, I am just passing on my bulk price to anyone looking for these cards. Anyone interested please email or call brandon@dpxsupply.com 954.461.4615  Paypal is preferred.  Thank you.  Brandon

Text me for real time screen shots what mine are running at be happy to share..

How many GH/s do these get?

840 to <900 for 290 and have a 290x running at 930 right now depending on how you configure them (eng 1000 mem clock 1500, thread 32765 on 290x) The 290x Tri-x in is a rig with Sapphire 290x's the Tri-x is running at 73c and the Sapphire non Tri-x is 83c without a fan blowing on them but one behind it drawing air away.
