I bought the video card for my HTPC, which is powered by a Core 2 Duo E6600 and has 6GB DDR2 Ram. Unfortunately, you can not gaze 3D Blu Ray in this connection. The CPU usage increases after the start of the Blu Ray to 100%, the GPU of the graphics card moves against it at 0%. Apparently the card or driver problems with the 3D rendering has. Normal Blu Rays against running with about 5% CPU utilization. Added to this is that when installing the driver on a freshly installed Windows 7 64bit "blue screens" showed up, only worked an older driver. Get it now try with a NVIDIA GT610.
