Wow...I purchased an A64 3200 and K8N for mywork rig. I was not expecting much of an oc, maybe 2.2 or 3. I hit 2.6 no problem on air. I could only get my A64 3500 to 2.6 on my Mach II. What a great little chip this is!
Anyway, I know many of you have seen tons of threads like this. Just sharing my exp. 
I only paid $170 for the setup. Well worth the $.
