Hi all,ive just picked up a Sapphire R9 390 today from OC (got it for £205) bargain.opened up the box and it comes with a HDMI cable,it also has 1 DVi-D port and 3 display ports.Im on a 1080p monitor at the moment but am grabbing a 1440p one soon.Im a bit confused as to which port should be used for maximum effect..Thanks
