I have put off downloading the version 2.0 documentation for a while now, largely as I cannot afford a board with compute capability 2 just yet. This weekend I eventually succumbed to temptation and downloaded the pdf.
For those of you playing with raytracers figure 5.4 on page 58 should be of particular interest :) Its nice to see how much the nice NVidia engineers are improving their products all the time. Now to scrape together my pennies for a 2.0 card... Still developing on a 8800GT isnt a bad idea as a lot of people have them - I'll just keep telling myself that for now :)
