First and foremost we know that when motherboards have the same parts installed that they are going to deliver results within a specific performance envelope. That being said the ASUS P8Z77 motherboard I have tested delivered excellent results when compared to another Z77 chipset motherboard in terms of just raw performance. Once you peel away the performance layers you have to look at the build process and the feature set used for the P8Z77 WS. As a workstation product you can guess that the feature set is decidedly oriented towards a business class environment. To that end ASUS has an initiative called 24x24 where the boards are targeted for use 24 hours a day for a solid 24 months to allow the consumer to have a a reliable platform long term."
