Adding Thunderbolt support to a desktop PC isn't as easy as dropping in an expansion card. Current Thunderbolt chipsets need to see a motherboard's display outputs, and they can't do that over PCI Express. A number of Asus' current Z77 motherboards provide a special header to make that connection possible. Now, the company has introduced a couple of new models with native Thunderbolt support: the P8Z77-V Premium and P8Z77-V Pro/Thunderbolt. The latter adds Thunderbolt to the existing Pro model, while the Premium is a little more upscale.
