I am trying to figure out what card would be the best for playing HD-DVD's on a HDTV. The 7900GS can be bought for around $150 and seems like a good HDCP capable card. Of course I would like to get an 8800 but I think that it would be overkill for just playing HD-DVD's and plus it is more than twice the money. Would the 7900GS be sufficient or would there be a better choice. Thanks in advance...
