btw the specs guy didn't say it but this only supports 2nd and 3rd gen intel processors. Also i didn't look it up yet but the board may not support all of the compatible b75 chipset processors. But if your interested in your possible options then here. http://www.cpu-upgrade.com/mb-Intel_(chipsets)/B75_Express.html
and also when he said pci 3.0 he was talking about the 32 bit lane not the 1x and 16x pcie lane. Those are both pcie 2.0. And also since this is msi the bios will be very nice and overclocking will probably be a cinch.
