SMP would be fine with 4 e5500 cores in the P5040 and the T1042, and I have doubts that more cores can be frequently saturated with common desktop computing tasks. Besides, I think it's a given that the non-SIMD per-clock performance of the e6500 is less than 22% higher than that of the e5500 so won't make up for the clock rate decrease.
