Hi , I am going to be building my first P.C soon and i am getting the GTX660Ti and i was wondering how I was going to set a dual display up as the GTX660Ti only has 1x HDMI port, for the second monitor will i need to get an adaptor or will it be fine, Also if i connect for example Displayport or DVI instead of HDMI, and one with VGA will there be sound issues?
