The board you listed is a Z68. There arent too many things that are different except that a Z77 board offers native USB 3.0 and PCIe 3.0.
The board you listed also has USB 3.0 but will require a BIOS update for it to work with the 3rd gen Ivy Bridge CPUs.
Basically it comes down to this..if you have a Z68 system and want to upgrade to the IB CPUs you just update the BIOS and press on. On the other hand if you do not have a z68 or newer build (IE... a new build) its better to just grab the faster and more furture proof Z77 board if it fits your budget.
