There is no getting around the fact that to run Eyefinity for gaming purposes (yes there are others!), you are going to need a powerful setup. Our Eyefinity arrangement will be running at a resolution of 5760x1080 so it stands to reason that at this huge resolution, a powerful graphics card will be required. That said, if you are running displays with odd resolutions such as the one used today, it stands to reason that you are not a millionaire and do not have the very best equipment available otherwise you would have gone and bought 3x30" 4K screens right? So then, we reached a middle ground (of sorts) and decided to run the R9-290X courtesy of Sapphire which is a much friendlier card on the pocket yet has sufficient grunt to run Eyefinity. Of course we didn't want to be CPU bottle necked so we opted to use our GPU test setup as the foundation for our test rig:



Eyefinity Test Setup



For benchmarking we will be using a modern selection of demanding, modern titles that will push our setup yet hopefully give us a good overview of what benefits Eyefinity has to offer each genre:

Battlefield 4
Thief
Company of Heroes 2
GRID: 2

Throughout the tests we used a resolution of 6400x1080 along with accompanying comparisons of both 2560x1600 and 1920x1080 to assess the performance hit you can expect by running Eyefinity. This was achieved by having two of the monitors hooked up via DVI with the centre screen running off HDMI. Not all of AMD's range have multiple mini-DP ports so we thought it important to attempt to replicate what you at home may encounter by running a combination of ports, to a combination of screens. While it is safe to say in an ideal situation you will be running a R9-295x2 with 3 matching screens all hooked up by DisplayPorts for the easiest of configurations, we understand that the vast majority of Eyefinity setups are bastardised configurations which usually results in the most problems which, after all, is what we are here to assess.
