The card is top for a HTPC, everything runs smoothly (Blu-ray and Blu-ray 3D). A bit annoying is the small fan is a little difficult to hear when low volume. But at normal room volume falls no longer on.
I had previously tested, a Radeon HD6450 with a 3D Blu-ray playback has not been possible because 3D CPU load went to 100% immediately after the launch of Blu-Ray.
With the GT610 and a Core2Duo E6400 and 6GB Ram utilization is around 45%.
