Okay, so 100 to 133 mhz is incremental. So is 66 to 100 mhz, but that doesn't mean gadget junkies and stupid people won't flock to the retailers and snap them up like the "miracle" tonics of the 1800's. I can't tell a darn bit of difference, even playing games, between my K6-2 350/128 MB/Banshee AGP system at 66 or 100 mhz.
