I'm running a pair of L5639's in my main server. Perfectly usable. Yes, the cores are relatively slow, but you get plenty of them.

I see one dual socket Westmere Xeon that's actually slower than the two you're complaining about (1/3rd as much cache, 5-20% slower clock), and a bunch of similarly ancient consumer-level junk.

I even spy an i7 920 in there. A 2008 first-gen Nehalem. That's a 130W CPU with terrible power management, how on Earth is that economical for them to deploy?!
