I think you have to use display port connector to get 60 hz. Over hdmi it's 30 hz. I know this is true for Asus. Not positive about Dell.
Yeah I'd be buying the Graphics Card specifically for the displayport connection, my motherboard and current gpu don't have one, I'm just wondering if DP 1.2a is the standard on these cards, there's no mention of it anywhere.
