From a cursory glance, I noticed some things:
1) The nVidia 500 and 590 chipsets are used, but not the 680i...? And the P965 chipset from Intel got the nod on both of the other two mobos? I know a lot of guys preferred the P965 over the 975X chipset, but why cut out the choices? Something, to me, smells fishy...
