You do need a powerful video card to translate the digital signal to a usable signal for the HDMI TV. But first you have to de-encrypt the information on the HD DVD/Blu Ray discs. This encrption, called AACS, is very CPU intensive. The method of encoding also has a bearing of the CPU power. MPEG-2 and VC1 both use the CPU for decoding the info. H264 uses the GPU.

Without the hardware of the GPU, only the most powerful overclocked CPU could handle full load of 1080P signal.
