    So how's the firmware? Does it have Secure Boot, does setting UEFI variables and changing boot order etc. work as expected?
    I have a similar model, also from MSI, but for Ivy Bridge. The UEFI was quite problematic at the beginning (in Windows, at that), but it was fixed in later firmware upgrades and now works just fine in all regards.

    On my case i have MSI H81M E33 but H81M E33 mobo its more cheapest than B85M E33 (on my country cost 50us ), but both maindoard have similiar size but my H81M E33 have HDMI (on my opnion its more important HDMI than DVI)

    Respect UEFI, i dont using that (on my case give troubles), i use legacy boot and not problems with my operating systems installed: Windows XP SP3 32bits, Windows 8 Pro 64bits and Linux Mint 16 32bits

    It would be a great article to compare how well the EFI implementations of the major board brands (ASUS / MSI / Gigabyte / Asrock / Biostar / etc) work under Linux.

    I know that Asrocks firmware wipes the efi table every firmware update, but has network updating. ASUS can only hold one entry in its EFI table persistently but doesn't wipe that between updates. Neither of them have a working EFI shell.

    B85 chipsets are nice. But I have read that if you pick an Asrock of the same model, your chances are higher of getting VT-d working. I also read that Asus support for VT-d is pretty bad. It might be enabled, but have missing ACPI tables of some sorts.

    This is all very confusing, because on the Intel chipset pages they only mention VT-d on Q85 and (I'm not sure anymore) 87 boards.

    I have a z87i Asus board that does vt-d just fine on my i7 machine.
