I am making my first pc and I haven't gotten down to choosing a mobo. I know you can put video cards, sound cards, and adapters in pci slots. But what confuses me is all the pci things, like this.....3 x PCI Express 3.0 x16 slots (PCIE2/PCIE4/PCIE5: single at x16 (PCIE2); dual at x8 (PCIE2) / x8 (PCIE4); triple at x8 (PCIE2) / x4 ) (PCIE4) / x4 (PCIE5). What does any of this mean? I am planning on running two of these in sli http://www.newegg.com/Product/Product.aspx?Item=N82E16814125443 . I also plan on using this http://www.newegg.com/Product/Product.aspx?Item=N82E16833166076 . Those three things though are the only things I plan on using in those slots. So what type and how many of these slots should I look for when purchasing a motherboard?

Solution
There are 3 PCI-E 3.0 16x slots.
PCIE2 PCIE4 PCIE5 are simply refering to WHICH slots.
One card in the 'PCIE2' slot will run with 16 lanes
A card in 'PCIE2' and 'PCIE4' (The setup you would have) Would run both cards with 8x lanes each.
Having 3 way SLI would have one card at 8x, and two at 4x lanes.
Nothing to worry about

The gfx cards will sit in the PCIe x16 slots. The wireless card will sit in any PCIe x1, X4, or x16 slot. (Best to keep it out of an x16 slot, tho)
PCI Express (PCIe) comes in different length slots depending on the available lanes. 1, 4, 8, or 16. The more lanes the greater the bandwidth (throughput)
PCI is the older legacy 32 bit slot. The devices that plug into them are fading away.

Which MB are you planning on using when you go to dual cards? It needs to be at least x8, x8 lanes for decent performance.

That would be a good board to do dual cards. It has x8, x8 lanes when 2 cards are in use: http://www.asrock.com/mb/Intel/Z87%20Extreme4/?cat=Specifications
Just stay away from a board that has its 2nd PCIe x16 slot rated at only x4 electrically.
