Under 200$ though, SB and AMD CPUs are pretty closely matched, and as a plus AMD processors can be OCed, while SB i3s can't move a MHz. Under 100$ one must be crazy not to buy AMD considering they have the best platform (SATA3 and USB3 under 100$/mobo) and the CPUs are at least on par with Intel, if not better.
So from my point of view, it is clearer than ever: sub 100$ AMD; 100-200 gray area, depends on the apps used and interest in OCing; over 200$ Intel.
Actually, it's more like starting at $170, they couldn't compete. It seems SB processors were purposely priced to compete with X6. i5-2300 -> 1055T; i5-2400 -> 1075T; i5-2500(K) -> 1090T.
Also, locked chips can overclock by around 400 MHz. By my estimate, taking Turbo into account, that's just enough headroom for even the junior i5-2300 model with all 4 cores stressed to match the performance of a Phenom II oc'ed to ~4GHz.
Below $170, it'll be AMD's domain. Clarkdales will be preferred by some but once it gets phased out, locked Core i3's won't be able to compete.
