Chipset drivers after install, if AHCI was enabled in the BIOS it would have installed default SATA drivers.
But no harm in updating them. Have no idea what Killer network manager is. HD graphics if you want to see more of the screen lol
If it's Win7 or 8 they may install generic LAN / sound drivers. You can install them if you want. But I dont bother. I just use the drivers windows installed
