Do i need to update my bios?

There will ne performance increase. BIOS updates are released when newer hardware such as CPUs come out years after the motherboard's release.

It is generally not recommended if you';re system is running fine, especially if you are not adding new hardware.

There's also always a risk when updating BIOS such as a power outage or file error and if the BIOS ROM chip can't recover itself, you'll have to semd the motherboard back if under warranty.
