Visiontek has created a dual GPU graphics card with two independent video controllers. This allows the graphics card to support up to four monitors simultaneously. However, unlike most Eyefinity options which use DispalyPorts for the connection, the HD 4670 x2 can do this through four dual-link DVI ports. This could be very beneficial to anyone with multiple DVI monitors and no means to tie them all together.
