Heh... Nehalem... Hmmm lets see, it has 8 cores with intergrated memory controller. Yep, I'd say it will need a different chipset. As far as the other Penryn support, its too soon to really say if it will work or not, not to mention it really isn't available to buy yet (Yorkfield/Wolfdale). Cause all I see is Kentsfield versions on NewEgg. And still leaves me the option to go to a quad.
Although its nice to finally see a Phenom chip at NewEgg.
