On an unrelated note, NDA will be lifted for the X1950 XTX and CrossFire Edition, and the X1900 XT 256MB edition TOMORROW.
Those three cards will be released on September 14, 2006. The prices for the X1950 XTX and CrossFire variants will be at $449 MSRP and $279 for the X1900 XT 256MB, respectively. All three cards will be HDCP compliant and the X1950's will feature quieter heatpipe coolers fashioned like Arctic Cooling's Silencer series while the X1900 XT 256MB will feature the stock X1900 reference cooler from ATI.
Here are some internal benchmarks from ATI. Of course, don't completely trust internal benchmarks as they might not be accurate. Wait for the NDA to lift and you'll start seeing reviews pop up all over the internet.
