the older chipset and bios are fine with windows 10. running the older z77 sabertooth here. the older chipset drivers are already built into windows 10. so it make for older pc not bad to upgrade to the newer os. if it runs windows 7/8 with no issue it should run windows 10 unless it a pre built. some older units wont without a bios update and some vendors are not doing that and give people small warings that the new os is not support.
