I was planning to purchase the Asus P8Z77-V LX as my motherboard, but after looking at the Asus P8Z77-LK, I was considering switching my choice.
Are there any features I would be missing out on by buying the LX, and is it worth the money to upgrade to the LK.

Thanks,
Robozman

Bump. Was planning to purchase soon.

The price difference on newegg is minimal; I'd choose the LK because it's more popular and comes with 2 PCI 3.0 slots.
