On PC part picker, it says "Some Intel Z87 chipset motherboards may need a BIOS update prior to using Haswell Refresh CPUs." At the expense of sounding like a total n00b, what does this mean, and will this be a problem? This is my first build, so I would appreciate any and all help and opinions about what this means. In case it is relevant, this is the full build: http://pcpartpicker.com/p/nY4LK8
