Recently upgraded from a Gtx 650 to a 760. With the 650 I had no issues but with the 760 the screen has a flickering but only when using the dvi output. I have no issues when I use the hdmi or display port.. my only guess as what the problem could me is the card itself. I've tried all the vsync options and no changes.. oh and it only has this issue while playing a game not when I'm using Windows for whatever.. anyone have this problem or know what the issue is? Thanks..
