Ok, so I bought a Z87 Motherboard and am already wishing I would have got Z97 after figuring out they are practically the same price and z97 just have a little more benefits to them. My Question is will I have to do a bios update for my motherboard running a i5-4690k? I also saw on my mobo it has a few stickers on it that say 1505 on the box and on the motherboard, does that mean it has that latest bios which will allow me to skip that process? Thanks!
