Please explain PCIe lanes to me

Ok, so I am currently eyeing three 1150 motherboards with thunderbolt:

http://www.asus.com/Motherboards/Z87DELUXEDUAL/
http://www.asus.com/Motherboards/Z87EXPERT/
http://ark.intel.com/products/70898/Intel-Desktop-Board-DZ87KLT-75K

Just looking at the features, the intel one is the more appealing, as it has an integrated TI 1394 chipset.

However, the expansion slots seem to be differently configured, and I'd like an opinion on those. I am currently building a new computer, main purpose being video editing, audio recording and a little bit of gaming. I am planning on buying only 1 video card, no need for multiple GPU etc. So most likely a PCIe 16x card.

I'd like your opinion on the expansion capability of these boards, as I don't quite understand the whole division thing, and what is really concerned. Is it only graphic cards? What about sound cards, or digital video capture cards?

Both Asus are specified as such: 3 x PCIe 3.0/2.0 x16 (x16 or dual x8 or x8/x4/x4), 4 x PCIe 2.0 x1

And the Intel one: Three PCI Express* 3.0 x16 graphics slots (switchable to x8 or x4), One PCIe* Mini Card slot with support for mSATA solid-state drive, Three PCIe x1slots, One PCI slot

Is there any difference between the Asus and Intel? (apart from the fact the Intel has one PCIe x1 less, and one legacy PCI instead)

Thanks!

They are essentially the same.

PCIe 3.0 bus at up to 16x (dual 8x)

And one more PCIe 2.0 at 8x OR 4x + 1x +1x +1x OR 1x + 1x +1x +1x

I assume the mSATA might consume part of that secondary PCIe 2.0 if it is occupied.
