Worldbench and Cinebench
With the exception of the office benchmark in Worldbench all of the Worldbench results are very consistent showing all of the Asus boards within a second or two of each other while being consistently faster than both the Intel and Gigabyte boards. The only board that was (slightly) an exception to that was the Maximus V Gene with noticeably better results in every test other than Winzip.
In Cinebench our Single Core tests were very close across the board. But when it came to the full CPU benchmark we did see interesting results. All of the Asus boards outperformed the Intel and Gigabyte boards, with the Maximus V Gene standing above the rest with an impressive jump considering all of the tests are done using the exact same equipment.
