ASUS P9X79 Motherboard Roundup
To get a better understanding of the X79 platform we have included Intel’s diagrams for the X79 chipset and the Z68 chipset:
While you look over both diagrams they do look very similar. However, there is a good deal of changes. The two main differences are that the X79 supports the new LGA2011 Sandy-Bridge-E processors and supports quad channel memory configurations while the Z68 supports the LGA1155 processors and supports dual channel memory setups.

Looking closely at the two diagrams you will notice that the X79 Chipset supports 40 lanes of PCI Express 2.0 for Graphics which will support up to five graphics cards in a 1×16, 2×8, and 2×4 configurations, that a big advantage over the Z68 which supports a mere 16 Lanes.
We also noted that while the Z68 Chipset supports the Intel Smart Response Technology the X79 has dropped this feature. We are not really shocked by Intel’s decision here since if you are paying $1000 for their Core i7 3960X processor, not to mention a new motherboard and a decent set of Quad channel memory you will most likely be installing one of the newer SATA III Solid State Drives for your OS.
