VisionTek also has a X1600 Pro 256MB model: http://www.visiontek.com/products/cards/hidef/1600pro.html
I can't say that I'm terribly happy with it. It was a big sluggish playing HD-DVD even with AVIVO enabled in PowerDVD.
On a side note, I've noticed that most current cards that have HDCP support also require massive (350 Watt+) power supplies. It would sure be interesting to me, someone who has a media center PC with a puney 300W power supply to know the available cards that don't have such strict requirements as the GeForce 7950s or the current GeForce 8000 series cards. Knowing nVidia, they're probably going to release some budget 8300/8600 cards that will have HDCP and PureVideo HD but they're probably a few months away at best.
What are you full pc specs?
