According to Guella's site, a Spitfire 550MHz will cost $79, a 600MHz $99, a 650MHz $140, and a 700MHz $175.

Athlon prices, as we have reported here in the past, will be aggressively pitched against Intel's offerings. The 1GHz will drop to $1071, the 950MHz will cost $722, the 900MHz will cost $589, the 850MHz will cost $429, the 800MHz will cost $323, the 750MHz will cost $242, the 700MHz will cost $187, the 650MHz will cost $163, and the 600MHz Athlon will also cost $163 as it is shuffled out of the equation.
