Today I speech with my friend in taiwan and I found that Kentsfield have 4 model after release but no price is available :
Kentsfield @ 2GHz 4MB
Kentsfield @ 2.33 4MB
Kentsfield @ 2.66 8MB
Kentsfield @ 3.00 8MB

Now whats the best way? wait for Kentsfield @ 2GHz FSB1333 Quad Core 4MB
(it can reach 3.2GHz easily) or go with Core 2 E6300 @ 3.2GHz??
