Hi, I've been looking into upgrading my current build, it's a pre built lenovo PC. I'd like to upgrade my GPU, PSU, motherboard and case (http://ca.pcpartpicker.com/p/W4cFJx). I primarily want to play overwatch and cs:go. On partpicker it says "Some Intel B85 chipset motherboards may need a BIOS update prior to using Haswell Refresh CPUs." will that be a problem?
