Adam and Jamie of Mythbusters fame are cool guys. I enjoy their program and find it oddly educational, in a sort of geeky-destructive way. But I have to admit that the following video of a demonstration they did at an Nvidia graphics card conference really impressed the heck out of me. The first part of the video shows their interpretation of computer graphics using a single CPU, and the second part is their version of a massively parallel GPU rendering.
I was starting to think that the tide might be turning away from ATI + AMD: my favoured platform for the last four years or so. Both Intel and NVidia have been ahead of ATI/AMD now for about a year in terms of top-end video card and CPU performance.
