I'm sorry -- you don't have the technical background required to make a technical comparison. Saying, "here are the theoretical FLOP numbers" says very little about performance. I stopped reading as soon as I read your silly CPU comparison.
For example, the theoretical peak FLOP numbers are about 2x what the PS3 has seen in the optimal case. This is with an application that can be parallelized across all of the SPEs. In a the average gaming case, I think the Cell would be unlikely to see more than say, 1/4th to 1/8th its theoretical peak (depending on the game and algorithms used).
