Difference between Asus P8Z68 LE & LX

[mjavid]

Hi,
Does anyone know how these are different (price and specs seem the same?)

Looks like the primary difference is the LE has a heatsink on some voltage doodads that the LX doesnt have.

looks like the LE has some usb3 headers that the LX doesn't, different audio chips, and the previously mentioned heatsinks
