Not an easy thing to do, as I've been looking into this for awhile.
But, I think I've managed to crack it. Dual Harpertowns (exact part determined by individual budget), and cheaper.A little over clocking is required though.

Two e5410s will overclock to at least 2.8GHz with stock cooling and only cost $275 a piece. Use a Skulltrail board and you might be able to get beyond 2.8GHz with a little better cooling.
