I recently just build a new setup with Asus P8Z77-V LK, this motherboard comes with UEFI boot and legacy BIOS boot support. So I tested install windows 7 in both mode, and I didn't find any advantage of UEFI consider it is a new technology been promoted quite a lot for recent years. The benefit I found is: a graphic BIOS setup, which is useless to most users if you don't OC. Even you did, I still find using keyboard to navigate through the menu is much easier than mouse. Faster boot time? very negligible, could be 31 seconds compare to 28 seconds. As I timed use my stopwatch, the value could include a few seconds human error as well. Support boot from > 2.2TB HDD? nowadays most user use SSD as boot drive so this really doesn't matter. GPT disk partition? don't see any benefit here compare to legacy MBR... Anyone can enlighten me what is the advantage of UEFI here? Thanks a lot!
