The Gigabyte EP45-DQ6 features might have had a few limitations but they were far out weighed by the functionality and performance of the board. In a lot of the testing we did against the older P35 chip set Asus P5KC we saw a 30% or more performance increase with the EP45-DQ6. The Matrix Raid Array we set up on 2 hard drives and partitioned to run dual boot XP/Vista worked perfectly and provided a superior transfer rate that exceeded 100 MB/s and after things got broken in was hitting 120+ MB/s in most cases.
