Earlier on today we took a look at AMD's latest and greatest graphics card, the Radeon 6990. In that article we looked at a number of performance aspects and various features the card offered but one item was missing, CrossFire performance as we were yet to receive a second card. That changes now though as we have one of the first retail branded 6990s in our test system and have combined it with the reference model to look at performance when gaming on one and three screens. This includes Dragon Age 2, Crysis 2 and of course the customary run through 3DMark 2011.
