core2solo, shit is real boi.
Well there were little to no differences between P2 and P3; thats why most mobo's were known to be P2/P3 (but didn't support FSB 133MHz out of the box (it had standard 100MHz), so you could argue P3 was just overclocked FSB to make it faster)
P3 @ 800MHz was already at socket 370 (and AMD was rocking the world at that time already with cheap durons and more expensive athlons little bit later; so there wasn't much reason to stay with intel at the time; not to mention p2/3 were power loud big hogs.)
i've seen some people manged to modify slot1 pcb to support socket 370 on top of it. It was nice hack back in the time.
