I'm getting my new PC soon so I'd just like to know if I have to (or should) update my BIOS. My motherboard is Asus p8z77-v. I've heard that with it you can update your BIOS before even installing the OS from a memory stick. Should I update it as I will be getting my hard drive for it a little later. Should I update it and will I benefit from it?

I agree. Latest BIOS (or UEFI) before you ever put the OS on it is best!

Have fun, be safe! Sláinte!

It is generally best to have the latest BIOS revision although it can be a dangerous procedure if you are updating in an area with frequent brown outs or electricity fluctuations. Corrupted BIOS flashes can render the chip useless, although with dual BIOS and whatnot these days it has become less of a worry. Make sure you have the computer hooked to a UPS during the update process.

I actually follow the simple philosophy: "If it ain't broke, don't fix it."

BIOS updates rarely break a functional system. Before they started introducing safe BIOS update protocols, the risk was having the power go out right in the middle of the flash. You'd have to send your computer back to the manufacturer to have it fixed. Now, companies like ASUS have made it so that all you need is a stick with the BIOS image on it.

Check to see what the update entails. It may not even be necessary to perform an update.

For instance:
Let's say ECS throws out an update to extend your motherboards socket 1155 support from just Sandy Bridge to both Sandy and Ivy Bridge. You use a Sandy Bridge CPU and have no plans on getting an Ivy Bridge in the immediate. Do you need that update? I think this actually happened with your motherboard on the P8Z77-V BIOS 1015 update back in May of 2012 which happens to coincide with the Ivy Bridge release.

In your case, the Asus p8z77-v has had a lot of Windows 8 compatibility updates. If you plan on installing Windows 8 at any point, then you might want to consider updating. My motherboard has also had similar updates, but I was able to install Windows 8 on it without any updates and to date I've not run into any issues. Unfortunately, most motherboard manufacturers are extremely vague in what their updates do, precisely. It might be possible to have an ASUS rep answer some questions for you.
