Summary: Asus deserves to be recognized, up there with Logitech and ioGear for products that work exactly as you expect with minimum fuss. Put together a small cute HTPC box for my bedroom with a $300 Win7 HP 2-core computer and Vizio's well-regarded 42" 120 Hz 3d model. Plugged this card and their Xonar sound card into the HP box, hoped it wouldn't fry the lil' power supply, and ... it works! Quite quiet.
Summary: Card not recognized by the the motherboard bios. A different brand nVidea based graphics card and other PCI-E cards were recognized without difficulty. The first contact finger's gold foil was visibly shorter than the other fingers' foil. However it appeared to be long enough to make contact even so, and foil marks indicated it was indeed making contact. Bottom line, one visible physical problem plus whatever was causing the bios to fail to recognize it.
Summary: Runs nice and cool. I'm cheap, so I wanted to have a good video card while also not running a race horse. Works great with NVIDIA drivers on Ubuntu and other forms of Linux (but for me - not right out of the box. I had to install them through the command line with: sudo apt-get install nvidia-current-updates && jockey-text -e xorg:nvidia_current ).
Summary: I am using the latest NVidia driver for Steam on Ubuntu with this card. It is in a rather older machine, but still solid. It also support vdpau with MythTV which allows me to watch uncompressed 1080p bluray videos at 9% CPU usage. Perfect for your HTPC.
Summary: This little addition was for a Media Center PC where the fan was dead on the factory video card. The built-in HDMI was a welcome addition as opposed to the DVI to HDMI converter. Hooks up to the Media Center beautifully. Resolutions fit most any TV settings. Heat is not an issue!
