ASUS P5B DELUXE support Kentsfield ???

[nope]

@ nope

so from that info you saying that it will support quadcore!

I dont see why not , the only reason why core 2 duo had to have thinbgs different was because of the FSB and voltages were lower than other boards.

But for the quad its just same as core2 duomeaning the FSB, most likely it will be a bios fix.

Also agree with what pingu says , I forgot about the other chipsets but they will all support the E4200 , that i reckon will be better than the core 2 duo, time will tell.

[nope]

thats the one , is not out how could you have it unless you have the engineering chip?

If you have £1200 then google it , they out there , somebody somewhere will sell them to you.
