The 25W, four core Xeon E3 1230Lv3

by Jeremy Hellstrom |
That said the Xeon doesn't fall too far behind in many tests and at $250 it is less expensive to slap into a Z87 motherboard and it will reduce your power bill somewhat.
It is a Haswell chip running at a peak speed of 1.8GHz which would be great for a small business or for a home server.
