Am I getting the right mobo?

Hi, I am new here and I am not sure if I posting this in the correct place so please move it if it. thanks

So I am building a new computer, my first build actually, and I am trying to decide on the correct mobo for pci express. So far I have chosen this one and my graphics card is this one Currently I am only planning on purchasing the single graphics card then getting a second card and crossfiring them after either a price drop or the one card is no longer good enough. The video card has PCI Express 3.0 x16 and the mobo I have has PCI Express 3.0 x16: 2 (x16/0 or x8/x8). Sorry if I entered that incorrectly I just cop+pasted from newegg. My question is once I add the second card will the video card only operate at PCI express 3.0 x8? Or am I reading it wrong? and if so will this be a bottleneck? should I choose a different mobo that can run two cards both at pci express 3.0 x16? Thank you very much for any help

EDIT: Also I am going to buy a i5-2500k cpu for the build. Will this work with pci express 3.0 x16? if not it is not a big deal because the ivy bridge cpu is only 20$ extra

    8x is the standard for two sli cards; don't think you'll find any boards with two 16x pci-e slots in sli mode. Either the 2500K or 3570 will work fine; heard mixed reports about overclocking ivy bridge, but the 2500k is tried and proven.

    You need to buy the 3570k CPU to enable PCI 3. If you install a 2500k, the slot will run in PCI 2 mode.
