ECS has developed and enhanced the boards with an exciting feature: Scalable D.G.E., which produces increased, supercharged 3D graphics performance and supports simultaneous display on up to four devices (D.G.E) when connected to two independent graphics cards. The added benefit of Scalable D.G.E. over ECS already established D.G.E technology is that it can also leverage ATI CrossFire technology which enables two PCI Express-based graphics cards connected together to work effectively in tandem to enhance overall graphics performance. Not to limit the users configuration options, the technology allows for any single PCI Express graphics card to be used where the need for a dual card set-up is not required.
