Ideally you would like to have the 9400/9500 type GPU that can do both h264 and VC1.
Initially you might think you do, since you'd like to playback bluray material in the future. But in fact, most of the time you'd be displaying h.264 from HDTV transmissions, and deinterlacing it, if it's 1080i. Not all the different GPUs can do the advanced (temporal) deinterlacing for 1080i material.
In most cases, a 9500gt is the better choice, since it can do just that, even though it doesn't support VC-1 decoding in hardware, while a 8400gs can do that, but not deinterlace it.
For a more thorough answer, have a look at the mythtv mailing lists.
That's all and well but you should be slapped for that last sentence.
