So I am looking to buy a new laptop well get it as sa present for xmas. Been doing some configuring at Dell and looking around on Newegg. From experience I know that my ATI cards 2900, 4850, 4350 have had no problems with sound over HDMI, and I remember in the past nVidia required a separate hookup and drivers were flaky. I'm looking at some laptop with either a 220M or a 230M, and I am wondering will these give me sound over HDMI with no problems, or should I go for a 4330, 4570, 4650?
