The only thing more fun that an XFX Double Dissipation R9 290X is two of them in Crossfire, which is exactly what [H]ard|OCP just tested.  These cards sport the familiar custom cooler though they are not overclocked nor is [H] testing overclocking in this review though they will revisit this card in the future to do exactly that.  This review is about the Crossfire performance of these cards straight out of the box and it is rather impressive.  When [H] tested 4K performance they could feel the frame pacing improvements the new driver gives as well as seeing these cards outperform the SLI'd GTX 780 Ti cards in every test; though not always by a huge margin.  The current selling price of these cards is about $100 above the MSRP but still come in cheaper than the current NVIDIA card; these particular cards really show off what Hawaii can be capable of.

"Take two custom XFX R9 290X Double Dissipation Edition video cards, enable CrossFire, and let your jaw hit the floor. We will test this combination against the competition in a triple-display Eyefinity setup as well as 4K Ultra HD display gaming. We will find out if custom cards hold any advantage over the reference designed R9 290X."
