I'm planning to build a HTPC for my living room. Which graphic card is the best for video playback, when it comes to HD and Blueray movies? I'm not going to play games or any other stuff. Just high def movie playback at full resolution. And of course, the fan noise is also an important issue. The more passive cooling, the better.
I wonder how the 4550 compares to the onboard GPU like AMD 780 chipsets. I did test a AMD 780 MB once, but I could sometimes see frame lagging during a movie playback at 1920x1080 resolution. Not so nice.
