Motherboard Drivers

I have  a asus z87-k motherboard.

What drivers should i get from the asus driver website?

Should i get all the drivers under SATA such as the intel smart connect thing and the intel rapid start thing?

Should i get any of the stuff under the utilities or the BIOS utilities heading?

Also, why are there no usb drivers for the windows 8 driver section?

When i extract the files, which option do i pick? Do i pick "setup"?

I would just go for the essential drivers, the chipset drivers, audio driver (unless you have a dedicated/USB sound card) and the sata driver is usually for use with windows in RAID/AHCI install modes
