Asus M5A97 R2.0 (don't get the LE version)
-better MB means more reliable, better voltage control, heatsinks on the mosfets, better power phase system, better overclocking, longer lived, better audio... so on and so forth.
That Asus has a 8+2 power phase system, heatsinks on the mosfets, is feature rich, high quality motherboard, which supports some good overclocking with 125W+ cpus.
