I am looking for a PCIExpress, Fanless video card for a HTPC build, Is there one model/series that really stands out in the under $100 price range? that is capable of Dolby TrueHD and DTS-HD Master Audio bitstreaming. Two cards i have been looking at are the ASUS ENGT440 DC SL/DI/1GD3 GeForce GT 440 and ASUS ENGT430 DC SL/DI/1GD3 GeForce GT 430, not sure what the difference is in these cards.
