You'd probably do better to PM him.
Anyway, although the 8500 has gotten better with later driver revisions I still say that nVidia has the clear upper hand. Even though the 8500 has the raw specs to beat the Ti500 across the board I don't think it'll ever happen because of nVidia's superb driver team.
Then there's always the issue of the Ti500 having better 3D IQ than the 8500 and that's unlikely to ever change unless ATi change the way their hardware works. nVidia's 3D rendering accuracy completely owns ATi.
