You can squeeze some money from the RAM going from 2133 to 1600 Mhz.
From these two areas, I'd spend more on the SSD and get a 128 GB unit of a higher quality line. Samsung 830/840, Vertex 4, etc.
Since the price of the P8Z77-V LK and the LX are approximately the same you should opt for LK, its a higher quality part.
