I just custom ordered my first gaming PC and I totally had a brainfart while building it. Will two R6870's in crossfire work on my monitor? ( Spectre E246W) It has 1 DVI, ! HDMI, and 1 VGA. Did I totally drop the ball by not ordering a monitor by not having one equipped with two DVI inputs or is this not a problem? I can't find a solution on the web and I would really appreciate the help!!!
