No specific mention of the 8800GT and 9800GT is a bit odd, certainly the former was incredibly popular. Also, a more detailed explanation about the change in core design after the 500 series would have been welcome, since it often confuses many who based judgement on shader count alone, especially when for CUDA the 580 beats the entire 600 series and all the 700s except the 780 Ti and Titan. Btw, the GF256 was based on SGI's tech, a mass market respin of IR which SGI should but stupidly didn't do.
