Let's just get serious here for a minute!! K8 is never gonna do 4GHz, the architecture is not going to suddenly jump through hoops because it got a die shrink and that is not what the shrink is about.
This is about Advanced Micro Devices changing their manafacturing process to 65nm, and that now starts with k8, but that doesn't suddenly make the chip faster or better, sure we may see a couple of hundred mhz added, but nowhere near 4ghz.
Let's just hope the chips can hit 3.5, cause 3.5ghz k8chips in my Quad Fx???:banana::banana::banana::banana: yeah, I'll take that!
