It won't suprise me if Valve waits to release this until after the debut of the R520, being as no current ATI card can run it. The R520 looks good from what I hear, and it does include Pixel Shader 3.0 (finally). This level will be a perfect demonstration of the power of the R520. I am going to wait until both ATI and Nvidia's cards have been out for a while before I make my decision this time.
