Sorry, Am new here but I've read (And love how through you are!) I have the 6970m in my M15x it works PERFECTLY! my temps are low and I'm able to play my games:) BUT i don't have any sound via DP, its a dell card, and the display shows up on the screen, but it says I'm using a "display port to dvi adapter" and must use a sound cable to carry over sound, but I'm using a display port to HDMI and it carries sound over on my desktop and all other computer, and did used to carry sound when i had my GTX 240m, but now it wont work, have i don't something wrong? Thanks, Justin
