Well they are relevant numbers if you are gonna use your console to do number crunching all day long. Yes, the PS3 is in fact the console with the fastest CPU on the market. This is a moot point.
I own a PS3 because I use it as a media center box as well as a game console. But I can understand why someone would want to fire up an NES or SMS or SNES or Wonderswan for that matter and play the games with which they are already familiar.
Anyway those numbers posted in >>56 are Folding@Home numbers. They show that there are PS3s out there crunching the numbers to help the scientific community really well. They are not comparative benchmarks. The reason there are no consoles up there is that PS3 is currently the only console that runs the Folding@Home program.
