I connected two monitors using an HDMI and VGA to DVI-I and I had no problems on an EVGA 570.
You will have to discern whether or not your monitors have DVI-I or DVI-D, or possibly a display port. The two similar ports are DVI-I and DVI-D, only DVI-I output slot on your card will accept a VGA-non-digital input, with an adapter. I believe DVI-I is still VGA not digital,, so I do not believe you can go from DVI-I to DVI-D. But Im not sure 100% on the DVI-I to DVI-D thing, so please check
