@wuyanxu: My guess is that 98% of people will NEVER use CUDA applications, so it's a non-feature for me. PhysX? Yeah, great... every game has that right. If you consider how much extra it's going to cost you to run a GTX4 card in terms of electricity, plus a case upgrade if you don't have an Antec 1200 or TJ07 (as you *WILL* need a high airflow case), as well as living with the high-speed fan, I think it's starting to look exceptionally poor for value. Add that it's >6 months late to market, not conclusively faster than the HD5 series (the GTX480 should be ahead of the 5970 given the extra development time, which it absolutely is not) and the fact that AMD will probably drop prices of the 5870/5850 when the nVidia cards are actually available to buy off the shelf and, in my eyes, you have a clear flop. Don't get me wrong, I'm no ATI fanboy, but I think it's very very hard to defend nVidia with Fermi.
